			<description><![CDATA[We present a novel simulation model for the 3D crosstalk of plasma displays, which is a partial leaking of the image for the left eye into the right eye and vice versa. It is known that the 3D crosstalk degrades the 3D image quality seriously. In plasma displays, active shutter glasses are used to realize 3D display capability, and the phosphor decay response and the slow rising response of the liquid crystal (LC) shutter lenses influence the 3D crosstalk. In this paper, we investigate the mechanism of 3D crosstalk on plasma displays, and estimate its characteristics using the proposed model. The experimental results illustrate that the proposed model can be used efficiently to optimize the synchronization condition between the display and the active shutter glasses. In addition, we verify the effectiveness of the proposed model by introducing a new material for shutter lenses??ferroelectric liquid crystal (FLC)??which has fast switching characteristics and can enhance 3D image quality<sup>1</sup>.]]></description>

			<description><![CDATA[The real-time parallel computation of histograms using an array of pipelined cells is proposed and prototyped in this paper with application to consumer imaging products. The array operates in two modes: histogram computation and histogram reading. The proposed parallel computation method does not use any memory blocks. The resulting histogram bins can be stored into an external memory block in a pipelined fashion for subsequent reading or streaming of the results. The array of cells can be tuned to accommodate the required data path width in a VLSI image processing engine as present in many imaging consumer devices. Synthesis of the architectures presented in this paper in FPGA are shown to compute the real-time histogram of images streamed at over 36 megapixels at 30 frames/s by processing in parallel 1, 2 or 4 pixels per clock cycle <sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131112]]></link>
			<description><![CDATA[In model-based camera tracking where camera poses are estimated in such a way that projections of edges on a known 3D scene/object model are aligned with close and strong edges detected in camera images, a projection usually has multiple candidate correspondences (or hypotheses) and there is little information on which one is the true hypothesis. This ambiguity makes model-based camera tracking unstable and inaccurate. Therefore, this paper proposes an adaptive edge detection method that models the gradients of true hypotheses as a mixture of Gaussian distributions, adjusts the parameters of an edge detector based on the model, and selectively eliminates false hypotheses. In our preliminary experiments, the method reduced the pose error and jitter of a testbed model-based camera tracking system by 27% and 2%, respectively<sup>1</sup>.]]></description>

			<description><![CDATA[3D crosstalk is a critical problem in the 3D display field. It appears as the double image and deteriorates the 3D image quality. This paper proposes an image processing algorithm that compensates 3D crosstalk. The proposed algorithm controls the gray level in the pixel area where 3D crosstalk occurs. 3D crosstalk compensation algorithm is implemented and verified on Field Programmable Gate Array (FPGA) merged in 3D PDP. The experimental results indicate an enhancement of 3D image quality by reducing 3D crosstalk<sup1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131114]]></link>
			<description><![CDATA[In this paper, we present a novel high dynamic range (HDR) imaging method using a single image. The existing multiple image-based HDR methods work only on condition that there is no camera and object movement when acquiring multiple, differently exposed low dynamic range (LDR) images. To overcome such an unrealistic restriction, we make three LDR images from a single input image using local histogram stretching. An edge-preserving spatially adaptive denoising method is also proposed to suppress the noise that is amplified in the histogram stretching process. Because the proposed method self-generates three histogram-stretched LDR images from a single input image, ghost artifacts that are the result of the relative motion between the camera and objects during exposure time, are inherently removed. Therefore, the proposed method can be applied to mobile imaging devices such as a mobile phone camera and a consumer compact camera to provide the ghost artifacts free HDR function in the form of either embedded or post-processing software<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131115]]></link>
			<description><![CDATA[Unutilized TV spectrum is soon opened up for use by unlicensed devices (UDs). The main concern is whether the unlicensed operations could cause harmful interference to the licensees. In this paper we present an evaluation framework that allows us to assess the quality of licensed service in the presence of unlicensed transmissions. In our model, the UDs can spatially reuse a channel and hence, two closest UDs are separated by the cochannel reuse distance. The licensed service quality is measured in terms of outage probability, which is also susceptible to channel fading and shadowing. We then derive the exact expressions for the outage probability under the following channel conditions: (i) Rayleigh fading, (ii) lognormal shadowing, and (iii) the two being superimposed. This is followed by numerical examples that demonstrate the possibility of restricting the interference caused by UDs by increasing the cochannel reuse distance<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131116]]></link>
			<description><![CDATA[High peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signal causes signal distortion, due to nonlinear high power amplifier at the transmitter, and affects received signal quality at the receiver. To reduce the PAPR, various PAPR reduction schemes have been developed. Of these schemes, the tone reservation (TR) scheme and the active constellation extension (ACE) scheme are used for commercial OFDM systems such as the DVB-T2 system. This paper presents an adaptive allpass filter (AAPF)-based PAPR reduction scheme. The AAPF scheme does not incur mean power increment and spectral efficiency decrement unlike the TR scheme. The AAPF scheme can be used with constellation rotation whereas the ACE scheme has a fundamental limitation with it. Comparison of the PAPR performance and the computational complexity with the TR scheme is made and discussed. Bit error rate (BER) performance demonstrates that adoption of the AAPF scheme does not affect signal reception quality at the receiver.<sup>1.</sup>]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131117]]></link>
			<description><![CDATA[Most recent mobile multimedia devices, such as smart phones, laptops and tablet PCs, are equipped with IEEE 802.11 Wi-Fi interfaces for broadband wireless Internet access. The multimedia applications utilized by end users strongly require guaranteed QoS. Resource availability checking during initial connection establishment and seamless handover is essential under such conditions. Several analytical models of IEEE 802.11 WLAN have been proposed to estimate achievable throughput. However, they do not consider rate adaptations with multi-rate retry and individual channel conditions of each station. This paper proposes a realistic model to estimate achievable throughput considering Minstrel rate adaptation and multi-rate retry chain. The proposed model also considers each station individually, since stations may have different frame error rates in a real environment and thus, select different physical rates for frame delivery. Frame error rates are carefully read from the hardware registers of each station and applied to the model for enhanced accuracy. The correctness of the proposed model was verified through a series of experiments in a real testbed environment with up to 20 stations with MadWiFi interface cards. The proposed model shows accurate results in terms of aggregated and per-station throughput in various channel conditions.<sup>1</sup>]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131118]]></link>
			<description><![CDATA[Wireless data transmission standards like 802.16e, 802.11n, employ Low Density parity Check (LDPC) codes for error control coding. The bit flipping decoding algorithms presents a tradeoff between the error correcting capability, decoding resources and the decoding time. Software based LDPC decoders provide adaptation capabilities in system parameters such as block size and code rate. In a real-time, low-power mobile environments, the Single-Instruction Multiple-Data (SIMD) processor currently used for video processing, could also be used for the LDPC decoding. In this paper, the implementationefficient, reliability ratio-based, weighted bit flipping (IRRWBF) algorithm is presented using a flexible softwarebased LDPC decoder. Compact data structures are proposed for performing the decoding using SIMD architecture. Based on the implementation on two commonly used SIMD architecture for mobile platform, it was found that the decoding speed can be increased by more than 2000% (using 64 bit SIMD registers with vector integer calculation) and 1800% (using 128 bit SIMD registers with vector floating point calculation). Experimental results for different code lengths of 802.16e and 802.11n show that decoding time in order of 1??10-3~10??10-3 seconds is achievable. Due to significantly high throughput and flexibility, the proposed design algorithm and data structure can easily be adapted to any energy-sensitive mobile devices employing SIMD processors<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131119]]></link>
			<description><![CDATA[Selected mapping (SLM) is an efficient peak-toaverage power ratio (PAPR) reduction scheme without signal distortion in orthogonal frequency division multiplexing (OFDM) systems. Therefore, it can be applied to mobile consumer electronics that are sensitive to high PAPR because of the limitation of the linear area of a power amplifier. However, enormous inverse fast Fourier transforms (IFFTs) are needed for the sufficient PAPR reduction performance, which cause the mobile devices with SLM scheme to become quite complex and reduce battery power consumption. In this paper, we propose a new SLM scheme that replaces the additional IFFT operations with a conversion of the other candidate OFDM signal. Simulation results show that the proposed scheme significantly reduces the computational complexity, while it obtains the better PAPR reduction performance than the dummy sequence insertion (DSI)-partial transmit sequence (PTS) scheme<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131120]]></link>
			<description><![CDATA[This paper presents the implementation and experimental evaluation of an advanced MIMO detector for wireless LAN systems. The proposed detector architecture is based on the well-known lattice-reduction aided MMSE method. Several optimizations at both algorithmic and architectural level are presented which result in an efficient VLSI design able to meet the timing requirements of a practical OFDM-based wireless LAN receiver while keeping complexity at moderate levels. Moreover, the detector offers built-in compensation for transmitter impairments such as nonlinear power amplifier characteristics, hence providing a full and cost-effective solution for practical systems. The described solution is implemented on an FPGA-based IEEE802.11n prototype and evaluation results comparing performance of both conventional MMSE and reduced-lattice detection under several propagation scenarios are presented. Experimental results show significantly lower error rates at the receiver for the advanced detector, or equivalently a lower number of required receiver antenna elements for a given performance target, hence resulting in lower cost, physical size and energy consumption,sup>1</sup>.]]></description>

			<description><![CDATA[As the key technology of Chinese national digital television terrestrial broadcasting (DTTB) standard, time domain synchronous OFDM (TDS-OFDM) utilizes known training sequence instead of cyclic prefix (CP) as the guard interval between adjacent inverse discrete Fourier transform (IDFT) blocks to achieve better system performance. Until now, TDS-OFDM was primarily used in downlink broadcasting. When TDS-OFDM is directly used in the uplink, it is difficult to eliminate the superposed interferences caused by different training sequences and IDFT blocks from multiple users. To solve this problem, a novel scheme called time domain synchronous orthogonal frequency division multiple access (TDS-OFDMA) is proposed in this paper. The novel space-time frame structure of the TDS-OFDMA scheme is proposed to achieve joint cyclicity reconstruction as well as joint channel estimation at the receiver. Simulation results show that the proposed scheme can achieve better bit error rate (BER) performance than conventional OFDMA system under highspeed mobile environments<sup>1</sup>.]]></description>

			<description><![CDATA[GINGA-Nested Context Language (GINGANCL) is a subsystem of GINGA, the standard for the Brazilian mobile broadcasting service, and it specifies the mechanisms and services used to enable various interactive data services. The integral part of GINGA-NCL is the NCL declarative language that provides non-invasive control of a multimedia presentation in time and space, as well as user interaction. In particular, one of its core competitive advantages over other existing technologies, such as Broadcast Markup Language (BML) and Open Mobile Alliance-Rich Media Environment (OMA-RME), is that it is substantially light-weight. Therefore, in this paper, we introduce an implementation of a GINGANCL receiver for mobile handsets.

			<description><![CDATA[This paper presents the developed orthogonal frequency division multiplexing (OFDM) baseband processor employing adaptive modulations to grouped subcarriers, and its demonstration in millimeter-wave wireless indoor links. Channel measurements and characterizations are performed in line-of-sight (LOS) office environments where the developed OFDM system is supposed to be used. The OFDM baseband processor utilizes 192 data subcarriers among 256 FFT numbers. To minimize bit-error-rate (BER) performance in frequency selective channels of millimeter-wave wireless indoor links, these 192 data subcarriers are grouped into 24 subcarrier groups and independently modulated according to channel characteristics in each subcarrier group. We demonstrate it incorporating with the developed 70 GHz selfheterodyne transceiver. BER measurements and maximum TCP throughput test are performed in practical millimeterwave indoor environments. The results verify the advantages of the proposed adaptive modulation in OFDM and show better BER performance as well as higher throughput performance than a typical OFDM system<sup>1</sup>.]]></description>

			<title><![CDATA[An enhanced dual carrier modulation for performance improvement in WiMedia UWB systems]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131125]]></link>
			<description><![CDATA[In this paper, we propose an enhanced dual carrier modulation algorithm to improve performance in WiMedia ultra-wideband (UWB) systems. The proposed algorithm, which is named as double dual carrier modulation (DDCM), uses additional precoding to the conventional DCM to transmit symbols over different subbands. By using DCM and additional precoding, the proposed algorithm exploits not only frequency diversity in one subband, but also frequency diversity between uncorrelated subbands, resulting in more diversity and better performance than DCM. We also propose the detection method of the proposed algorithm by sharing the modified dual carrier modulation (MDCM) detection block which is included in WiMedia UWB systems. The proposed detection method reduces hardware complexity by combining the MDCM detection and the proposed algorithm detection. Simulation results of applying the proposed algorithm to WiMedia UWB systems show that the performance was improved by 1.5 dB and transmission range increased by 0.5 m in CM1 at a PER of 1%, compared to DCM.<sup>1</sup>]]></description>

			<description><![CDATA[Developments in outdoor free space optical (FSO) communication between buildings using rooftopmounted units are limited by Point-to-Point wireless links. We propose a space and time division multiple access scheme to perform Point-to-Multi-Point communication employing reflectors. A single reflector controlled by a stepping motor and an array of fixed reflectors are used. The reflection characteristics of the reflector are measured. The relationship characteristics between the static angle error of the stepping motor, the beam fluctuation, and the communication distance are demonstrated. The received optical powers are compared on using one or two reflectors while considering the angle of incidence at the surface of the reflector. Moreover, the received power, the bit error rate and the throughput of the experiment system are measured. In addition, the throughput characteristics of the proposal scheme are made clear by experiments. The result of the experiment shows that the new scheme can provide a low-cost and efficient method for Point-to-Multi-Point FSO communication<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131128]]></link>
			<description><![CDATA[In this paper, we focus on the design of bit mapping scheme to improve the error-control performance for the second generation digital video broadcasting-terrestrial (DVB-T2) standard. Generally in the case of low-density parity-check (LDPC)-coded modulation system, the nonuniform bit reliabilities inherent to the high-order modulation and irregular LDPC code imply the mismatch between the decoder and the demodulator. Hence, the bit mapping is plugged between the two modules to match the unequal error protections (UEPs) of different coded bits to different modulation levels. This scheme gives a remarkable performance improvement with no added complexity in the bit-interleaved coded modulation (BICM) system. By performing the curve-fitting on the extrinsic information transfer (EXIT) chart, we propose a DEMUX design methodology to improve the bit mapping scheme. Design examples are given for the DVB-T2 system under the AWGN channel as well as the Rayleigh channel. Simulation results indicate that the proposed DEMUX schemes can even surpass the performance of the DEMUX operation specified in the DVB-T2 standard<sup>1</sup>.]]></description>

			<description><![CDATA[This paper proposes a new soft-reliability information-based post-Viterbi processor with advanced noise-robustness for reducing probability of miss-correction and no correction of a conventional soft-reliability-based post-Viterbi processor. Among all likely error starting positions for prescribed error events, the two schemes are equal to attempt to correct error-type corresponding to a position with minimum one only if there exist positions where a soft-reliability estimate is negative. The main difference between the two schemes is how they acquire the softreliability estimate. The soft-reliability estimate of the new scheme is obtained through the elimination of the noisesensitive component from the log-likelihood ratio of the posteriori probabilities, which is the soft-reliability estimate of conventional scheme. As a result, the new scheme is based on more reliable soft-reliability information so reducing the probability of miss-correction and no correction.]]></description>

			<description><![CDATA[We propose an optical wireless indoor localization using light emitting diodes (LEDs) and demonstrate it via simulation. Unique frequency addresses are assigned to each LED lamp, and transmitted through the light radiated by the LED. Using the phase difference, time difference of arrival (TDOA) localization algorithm is employed. Because the proposed localization method used pre-installed LED ceiling lamps, no additional infrastructure for localization is required to install and therefore, inexpensive system can be realized. The performance of the proposed localization method is evaluated by computer simulation, and the indoor location accuracy is less than 1 cm in the space of 5m ?? 5 m ?? 3 m.<sup>1</sup>]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131131]]></link>
			<description><![CDATA[Performance of the narrowband power line communication (PLC) is significantly degraded by the impulsive noise with very large amplitudes and short durations. In practical applications, the simple memoryless nonlinearity techniques (Clipping, Blanking, and Clipping/Blanking) are often used in order to mitigate the effect of the impulsive noise. In this paper, we propose an optimal Clipping/Blanking technique for impulsive noise reduction in narrowband (9-490 kHz) PLC system. This optimal technique is based on the minimum bit error rate (BER) search. To this end, we have derived the transfer function of a typical low voltage (LV) PLC network using the common bottom-up approach and scattering matrix method. Our simulation results, in terms of BER versus signal to noise ratio (SNR), show that the proposed technique slightly improves the BER performance of the narrowband PLC system for smart grid applications and two-way communication between smart meters and utilities<sup>1</sup>.]]></description>

			<description><![CDATA[Recent advancements in smart home systems have increased the utilization of consumer devices and appliances in home environment. However, many of these devices and appliances exhibit certain degree of heterogeneity and do not adapt towards joint execution of operation. Hence, it is rather difficult to perform interoperation especially to realize desired services preferred by home users. In this paper, we propose a new intelligent interoperability framework for smart home systems execution as well as coordinating them in a federated manner. The framework core is based on Simple Object Access Protocol (SOAP) technology that provides platform independent interoperation among heterogeneous systems. We have implemented the interoperability framework with several home devices to demonstrate their effectiveness for interoperation. The performance of the framework was tested in Local Area Network (LAN) environment and proves to be reliable in smart home setting<sup>1</sup>.]]></description>

			<description><![CDATA[Smart lighting research traditionally focuses on conventional incandescent and fluorescent luminaries. However, in addition to its higher energy efficiency and longer lifetime, Solid State Lighting (SSL) offers better control of spectral, spatial, temporal polarization, and color properties of light. Combined with the recent developments in smart environments research, SSL utilizing Light Emitting Diodes (LED) creates a new playground for user-light interaction. We present a novel illumination model for SSL and implement this model on a wireless sensor network (WSN). The light sensors and actuators in the WSN provide services for sensing illumination changes and dynamically adjusting luminary brightness according to user preferences. Experiments conducted two key scenarios, i.e. reading and watching TV, show that the preferred illumination levels in an activity space can be achieved and maintained, irrespective of external light variations<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131134]]></link>
			<description><![CDATA[All commercial remotely controllable home appliances consume electric power while in standby mode waiting for a remote signal. This paper presents a new remote control system that consumes absolute zero power in standby mode. In this system, the home appliance is physically disconnected from the AC power line by a latch-type power relay in standby mode. When a laser beam is emitted from a remote controller to turn on the home appliance, the photovoltaic array mounted on the home appliance receives and accumulates the light energy in a storage capacitor. An autonomous connection circuit is devised and used to separate the storage capacitor from the power relay to prevent discharge during the light energy accumulation stage. When the proposed remote control system is implemented on a 190 W commercial television, use of a 15 mW infrared (830 nm) laser light for 620 ms turns it on at a distance of 2 m in a completely dark room. It can then be turned off using commercial remote controller<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131135]]></link>
			<description><![CDATA[This paper describes the development of networkbased humanoids to provide services in the home environment. For successful service in more intelligent and varied environments, various robot sub-systems need to be coordinated effectively. Thus, this paper also introduces a coordinated framework which makes robot-human interaction while executing various tasks by means of various robots. Using a task script, an operator can easily describe tasks and regulate actions of the sub-systems while a robot is performing the task. Furthermore, the control system of a robot must operate efficiently to ensure a coordinated robot system, so the realization of an IEEE-1394 real-time distributed control system and a motor controller for a humanoid robot are introduced. Many algorithms have been developed, and the following technologies are described herein: autonomous biped walking; real-time modification of collision-free paths; and interaction ability with humans and environments, such as face, voice, or object recognition. The results of the demonstration show that humanoids can execute tasks efficiently and are suitable to provide services in human environments, such as restaurants or homes.<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131136]]></link>
			<description><![CDATA[It is highly desired to employ a checkpoint and rollback scheme on a mobile consumer device for fault tolerance, because spatial fault-tolerant schemes such as hardware replications cannot be used. We can reduce the loss of computation of a process in the presence of failures by periodically saving the process??s state on stable storage as a checkpoint and rolling back to the latest checkpoint when a failure has occurred. However, a mobile consumer device is not considered to have sufficiently large and stable storage to store its checkpoint data. Therefore, a remote checkpoint technique is preferred in wireless environments in which the checkpoint data of a mobile device is kept in a remote checkpoint server instead of the mobile device. Dense checkpoints incur frequent wireless transmissions whereas coarse checkpoints increase the loss of computation. Many checkpoint research papers have tried to minimize the expected execution time. However, an effective solution which minimizes the energy expenditure should be also provided, because battery power is one of the most critical resources of a mobile device. In this paper, we propose the energy-aware optimal checkpoint interval in wireless remote checkpoint environments. We develop a stochastic model with Markov chain and then derive the optimal value. For the practical evaluation, we conducted not only analytical estimation and simulation but also experimental measurements by implementing on a real test-bed.<sup>1</sup>.]]></description>

			<description><![CDATA[We present a new computer interface that combines gaze tracking with brainwave measurements in an integrated head-mounted device. This interface is novel in the following four ways compared to previous works. First, because the system is designed as a single head-mounted device, both the brainwave data and eye images for gaze tracking can be acquired by wearing only one device that includes a sensing node and an eye image-capturing camera. Second, the noise in the brainwave data caused by blinking is removed by a blink detection system in the eye camera. Third, the sensitivity of a gaze-based navigation speed is appropriately controlled on the basis of the level of attention estimated by analyzing the brainwave. Fourth, performance and usability of the interface are validated by objective evaluating and subjective surveys. From experimental results, we confirmed that the proposed system shows promising performance and usability as a new computer interface<sub>1</sub>.]]></description>

			<description><![CDATA[This paper describes the design and implementation of a multimedia home gateway for threescreen television (3STV) service. The proposed in-home wireless network uses scalable video coding (SVC) and unequal error protection with Raptor forward error correction (FEC) for maximizing the quality of experience (QoE) over the variable-bandwidth, error-prone wireless network. The gateway incorporates (a) dynamic SVC layerswitching, which enables the server to perform selecting appropriate layers from SVC bitstreams, (b) adaptive Raptor FEC, which controls the overhead of Raptor FEC according to packet loss rate (PLR), (c) an efficient combination of (a) and (b), and (d) slice group-based selective streaming in the overall gateway architecture. The paper explains the home gateway architecture as well as experiments for performance evaluation as compared to that of traditional SVC streaming. In the experiments conducted, gains in video quality vary from 2 to 5dB in peak signal-to-noise ratio (PSNR), with corresponding subjective improvements. Overall reductions of bit rate at the input to the home gateway vary from 28% to 36%<sup>1</sup>.]]></description>

			<description><![CDATA[In a multimedia environment composed of various analog and digital devices, such as a home network, the performance and role of the gateway responsible for efficient data transfer between devices, as well as between the device and the internet, is becoming increasingly important. In particular, from inside the gateway, the effective arbitration among multi-channel stream data that are transmitted simultaneously will directly influence data delivery efficiency. In this paper, we propose MSCA (Multimedia Stream Channel Arbiter) that arbitrates the multiple multimedia stream channels needed inside the gateway. MSCA consists of several hardware components and arbitrates multiple MSD (Multimedia Stream Data) that have various characteristics in real time. In addition, MSCA has high practicality of communication among bus, memory and peripheral devices via DMA or stream buffers. Implementation and evaluation of MSCA confirms its good performance in stream packet arbitration. MSCA is suitable for the FPGA or ASIC design in terms of circuit size.<sup>1</sup>.]]></description>

			<description><![CDATA[Due to a growing number of high bandwidth applications today (such as HDTV), and an increasing amount of network and cloud based applications, service providers need to pay attention to QoS in their networks. We believe there is a need for an end-to-end approach reaching into the home as well. The Home Gateway (HG) as a key component of the home network is crucial for enabling the end-to-end solutions. UPnP-QoS has been proposed as an inhome solution for resource reservations. In this paper we assess a solution for automatic QoS reservations, on behalf of non-UPnP-QoS aware applications. Additionally we focus on an integrated end-to-end solution, combining GMPLS-based reservations in e.g., access/metro and UPnP-QoS based reservation in the home network<sup>1</sup>.]]></description>

			<description><![CDATA[The link layer is one of the key differentiating functions in a DVB-H receiver. In order to differentiate between silicon solutions, manufacturers can choose between basic or advanced link-layer implementation concepts, resulting in modest or excellent data retrieval performance, respectively. Hence, objective performance evaluation, which proves the quality of the link layer implementation, is an essential step to validate product robustness. This paper presents techniques for validation and verification tools to evaluate the DVB-H link-layer robustness. The proposed techniques for robustness testing are capable of generating both regular and extreme signal conditions. Furthermore, we also discuss an efficient analysis tool required to inspect (1) the IP-based output data, (2) Service Information and (3) Program Specific Information of the link layer.

			<description><![CDATA[Recent developments in publically available webbased Geographical Information Systems (GIS) and the availability of low-cost integrated General Packet Radio Service (GPRS)/Global Positioning Systems (GPS) modem have enabled the development of embedded stand-alone home monitoring systems. This paper presents the design, implementation and testing of a home-monitoring system that utilizes online Map from a GIS in conjunction with the readily available public satellite-based GPS, and GPRS mobile networks. In addition to detecting intruders, the system allows a home owner to remotely monitor various critical home sensors status including those tied to fire, flooding, and gas leaks. Home owners can monitor their homes via their mobile phone or by using the Internet. This system can also be utilized by security firms, civil defense organizations and municipalities to continuously monitor and locate troublesome spots in residential neighborhoods and compounds using free GIS Maps<sup>1</sup>.]]></description>

			<description><![CDATA[Many communication standards are available to set up consumer home networks. An intelligent combination of wired and wireless communication technologies allows exploiting many technology specific advantages while compensating disadvantages. Such a convergent digital home network infrastructure increases robustness, coverage range and availability of applications and services. In this paper, we discuss the general concept of such home networks. We present the Inter-MAC convergence sublayer as a very first approach to this concept. With the help of a typical scenario we demonstrate its feasibility. The recently initiated standardization activity IEEE P1905.1 is introduced. A global standard for convergent digital home networks can be the basis for a user-friendly network of consumer electronic devices in the home.]]></description>

			<description><![CDATA[Due to the limited bandwidth resource in WiFi networks, it is challenging to keep media streaming persistent at the existence of other competing traffics for the quality of consumer experience. The coordination of multiple media flows (e.g., rate adaptation, scheduling, etc) thus plays a crucial role for persistent media streaming without hurting other flows. In this paper, by employing the notion of CORE (COngestion Residual timE), we propose a distributed coordination scheme of multiple media flows for practical WiFi networks with diverse mobile smart devices. With this proposed coordination scheme, every mobile smart device controls the rates and the sequence of packet transmissions for all competing flows in a distributed manner. From extensive experiments with a realized prototype, the proposed scheme provides better quality of experiences by maintaining the persistency of media quality without hurting other competing flows<sup>1</sup>.]]></description>

			<description><![CDATA[Flash memory and magnetic disks are two widely used forms of non-volatile storage in consumer electronics. Both forms of storage have their advantages and limitations. The present study describes the design and implementation of a unified flash memory and hard disk translation layer (FDTL) to improve the performance of hybrid storage containing flash memory and disk drives. In this scheme, randomly accessed and frequently read data are mapped into a flash device, whereas sequentially accessed, frequently written, and cold data are mapped into a disk drive. FDTL is a good fit for several kinds of consumer electronics that demand large capacity storage and require high throughput, low energy consumption, and low cost. A trace-driven simulation was implemented to evaluate FDTL. Experimental results show that the I/O performance of FDTL is superior to other storage schemes with similar capacity. FDTL increases the throughput by over 40% and saves energy by 28% compared with other storages schemes<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131147]]></link>
			<description><![CDATA[NAND flash memory, which is widely used as a storage medium for mobile devices because of its lightweight, shock-resistant, silent, and energy-efficient characteristics, lacks an over-write operation. Therefore, NAND-based storage devices deploy a flash translation layer (FTL) to emulate the over-write operation with out-of-place updates. However, as out-of-place updates write data to new unwritten spaces, clean spaces eventually become scarce. This initiates a garbage collection process that accompanies several NAND writes and erases. Thus, it is important to reduce the latency and frequency of garbage collection, which is a primary aim of the present work. The central idea is to cluster hot and cold data separately to reduce the number of valid pages in a victim block at the time of garbage collection. Reducing the number of valid pages of the victim block contributes to the reduction of both the latency and frequency of the garbage collection process. Trace-driven simulations show that the proposed hot/cold clustering improves write throughput by up to 18%<sup>1</sup>.]]></description>

			<description><![CDATA[The performance and lifetime of highperformance solid-state drives (SSDs) can be improved by data compression, which can reduce the amount of data physically transferred from/to flash memory. In this paper, we present our experience of building a high-performance solid-state drive using a hardware accelerated compression module called BlueZIP. In order to fully exploit the BlueZIP module, we devise a compression-aware flash translation layer (FTL), called CaFTL, which supports compressionaware address mapping and garbage collection for BlueZIP. For poorly compressed pages, CaFTL supports selective compression so that unnecessary compression can be avoided. We have implemented a complete SSD prototype with BlueZIP on an FPGA-based custom SSD platform and evaluated its effectiveness using realistic workloads. Our evaluation results show that BlueZIP can increase the lifetime of the SSD prototype by 26% as well as improve read and write performance by 20% and 27%, respectively, on average<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131149]]></link>
			<description><![CDATA[A Flash Translation Layer (FTL) emulates a block device interface on top of flash memory to support traditional disk-based file systems. Due to the erase-beforewrite feature of flash memory, an FTL usually performs outof- place updates and uses a cleaning procedure to reclaim obsolete data. The FAST (Fully-Associative Sector Translation) FTL is one of the most well-known FTLs and has been used in many previous studies. It reserves a small portion of the flash storage as the log area and uses the blocks in this area (i.e., log blocks) to accommodate data overwrites. Among all the log blocks, one (called the SW log block) is used to accommodate sequential overwrites, while the others (called RW log blocks) are used to accommodate random overwrites. In this paper, two techniques are proposed to reduce the cleaning cost and hence to improve the performance of FAST. The first technique reduces the cost of RW log block reclamation by utilizing efficiency-driven cleaning policies, and the second technique replaces high-cost SW log block reclamation with low-cost RW log block reclamation. We have implemented the proposed techniques on the FAST FTL as well as the HFTL, an FTL based on FAST. The simulation results on six real/benchmark-based workloads show that the proposed techniques significantly reduce the cleaning cost, by up to 97.64% in FAST and 66.80% in HFTL, demonstrating the effectiveness of the proposed techniques.<sup>1</sup>]]></description>

			<description><![CDATA[Flash memory can be classified into NOR type and NAND type. The NOR type memories enables fast reading with byte level I/O is developed into memory for code storage such as ROM BIOS. The NAND type memories cheaper than NOR type and therefore more widely used to larger scale systems. This paper proposed the new file translation system by making a new file structure which can decrease write operations. This file structure reduced write operation frequency of flash memory in file system layer. We can reduced write operation rate because of a write operation rate can be improved the efficiency of file translation operations. Flash Translation Layer (FTL) is to mapping a logical data address to a physical data address in flash memory, its designed to realize erase policy of data in order to perform write operation. The FTL suggests fast erase algorithm reduced write operation through a new file system structure and FTL programming. In addition, we have made the oldest data clean algorithm and then, the most recent data maintained longest as a result of experiment that the recent applied program. In this result, Data tend to be implemented again through the concept of regional and time space which appears automatically when applied program is implemented. This work proves the efficiency of the file system of NAND type flash memories through experiments. Through experiment and realization of the Flash file system, this scheme proved the efficiency of NAND-type flash file system which is required in an embedded system.]]></description>

			<description><![CDATA[Recently, NAND flash memory has been widely adopted as a storage medium in various devices such as mobile phones, MP3 players, and digital cameras. In particular, Solid State Drives (SSDs), which are composed of multiple NAND flash memories, have gradually replaced hard disk drives (HDD). However, SSDs have an inherent weakness stemming from NAND flash memory and its complex architecture. This phenomenon makes it difficult to analyze and optimize the performance of SSD controllers. To overcome this weakness, highly accurate system simulations are needed for exploring architectural parameters to maximize the performance during the design phase. In this paper, we implement a simulator that considers all of the hardware components in SSD to assist in generating quantitatively accurate analysis when an algorithm or controller is realized. This simulator models the detailed characteristics of hardware components such as operation clock frequency and resource conflicts in order to represent SSD in great detail. In the experiments section, we verify the impacts of interface speed, page size, and other configuration parameters by using this cycle accurate simulator. These analysis results can then be used as raw data for optimization.<sup>1</sup>]]></description>

			<description><![CDATA[Flash memory has been widely used as storage media in consumer devices, whereas its erase-before-update characteristic degrades its performance. Buffer and FTL (Flash Translation Layer) are two important techniques to improve the performance of flash memory. However, in the traditional architecture, the buffer and FTL work independently, resulting in an information gap which affects the efficiency of garbage collection in flash memory. This paper proposes a new architecture to bridge the information gap between the buffer and the FTL. In the new architecture, the buffer manager provides several replacement candidates instead of one to the FTL, and the FTL makes and performs a decision according to these candidates and the physical information of flash memory. Experiments show that the new architecture can reduce the garbage collection overhead by up to 40%.<sup>1</sup>.]]></description>

			<description><![CDATA[Mobile robots are now widely used in various surveillance and security applications. But most of them are wheeled and tracked robots that can not work well to overcome stairs, doorsills and other obstacles in cluttered indoor environments. This paper presents the design and implementation of a new indoor security system with a jumping robot as the surveillance terminal. The jumping robot, a gateway and some pyroelectric infrared (PIR) sensor nodes form a ZigBee wireless sensor network (WSN). The sensor nodes are installed above the doors and windows of the house to detect intruders and send intrusion detection messages to the robot. The robot can jump to the sensor coverage area to take photos and send them to the gateway and the home server. The remote house owner will get these photos through Internet. A prototype system has been implemented and some performance tests have been done. Experimental results show that the robot can jump up on a desk of 105cm high to perform the surveillance task. A 3k-byte captured photo can be transmitted to the gateway in 3.68s with 0.1% loss rate by 5 hops<sup>1<sup>.]]></description>

			<description><![CDATA[A new block matching algorithm and its VLSI architecture for performing Motion Estimation (ME) are presented in this paper. In the reported fast two stage search algorithm, ME is performed in two stages. In the first stage, pixel truncation is used. In the second stage, ME is performed with full pixel resolution with an adaptive search pattern. The main advantage of the proposed algorithm is the inclusion of an early termination mechanism to reduce overall power consumption for the resulting architecture. The paper also introduces a suitable architecture to implement the proposed ME algorithm. In this architecture, a new memory management scheme has been proposed so that different bit planes can be accessed at different stages of ME from the same memory module. It has been shown that the proposed architecture can save approximately 27% power compared to another recently reported architecture. The proposed architecture can therefore be considered suitable for portable, battery-powered video consumer devices<sup>1</sup>.]]></description>

			<description><![CDATA[A camera shake of the relative motion between cameras and original scenes often occurs during a shoot, resulting in blurred images. This paper presents a method of restoring blurred images based on patch-based PSF (Point Spread Function) estimation and channel-dependent image deblurring. Initially, a pair of noisy and blurred images is acquired by consecutive shooting under short and long exposures to more accurately estimate the 2D trajectory formed by the camera shake, which is also known as PSF. From the noisy image, one patch with strong edges is extracted using gradient operators and the corresponding blurry patch is found within the blurry image. The boundaries of both patches are padded in a specified tile pattern to prevent the appearance of vertical or horizontal lines due to boundary discontinuity. Tikhonov regularization is then iteratively conducted on Gaussian pyramid images with adaptive noise thresholding to get the optimized PSF. Finally, the color conversion of the blurred image into a luminance and two chrominance images is done to apply the channeldependent image deblurring where the spatial resolution of the chrominance images is reduced based on the natural gradient distribution to abandon the valueless data regardless of the restoration quality. Moreover, another artificially blurred image made by the convolution of the known Gaussian PSF and the noisy image is used to reduce undesirable ringing-artifacts and increase the sharpness. The experimental results show that the proposed method can provide more improved PSFs and restored images accompanied by the reduction of computing time and ring artifacts<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131156]]></link>
			<description><![CDATA[In this paper, an adaptive two-direction pitch tracking algorithm for multiband excitation (MBE) vocoder is proposed. Instead of the multiple constraint equations, a difference inequation is constructed. The adaptive adjusting model of the difference threshold is established by utilizing the information including voicing decisions, pitch estimate, and multiple pitch error identification of the previous frame. To identify the multiple pitch error, an approximate corrective matching error measure from the spectral analysis-bysynthesis (AbS) method is utilized. Because the difference threshold can be adjusted adaptively, the proposed algorithm can efficiently avoid continuous multiple and continuous submultiple pitch errors. Moreover, the proposed algorithm almost needs no additional time complexity and computational complexity, so it can easily be implemented in actual systems. From the experimental results, it is justified that, the proposed algorithm outperforms the conventional algorithm, improving the accuracy of the pitch estimation and displaying excellent robustness to different speakers and white Gaussian noise conditions<sup>1</sup>.]]></description>

			<description><![CDATA[In this paper, new k factor decision method and highlight compression operator are proposed to enhance the appearance and naturalness of rendered High Dynamic Range (HDR) images. The retinex algorithm is one of the outstanding local operators, which well preserves local contrast in highlights. However, the retinex algorithm gives a worse overall appearance and undistinguishable dark area contrast than global operators or other local operators in some cases. The most prominent improvement of the proposed method is that the decision method of the k factor, which is one of the parameters in retinex algorithm, is proposed by using the dynamic range in images. The proposed parameter decision method enhances the overall quality and preference of the image and solves any parameter setting problems. Also, dark area details become more distinguishable by the highlight compression operator. According to the results of many HDR image experiments, the proposed method shows better rendering in terms of naturalness and dark area details than the previous tone-mapping algorithm.<sup>1</sup>.]]></description>

Firstly, depth video and its associated texture video in common temporal-spatial domain (CTSD) are transformed into coordinate transform domain (CTD). Secondly, depth pixels are classified with the aid of the associated texture pixels. Then, the luminance of each pixel in the same class is smoothened by using low-pass filter. Finally, the smoothened depth video in CTD is inversely transformed to CTSD. Experimental results show that the bit rate is saved by the depth video preprocessing algorithm, ranging from 3.15% to 37.94%, while the proposed preprocessing algorithm keeps the rendering quality of virtual view images<sup>1</sup>.]]></description>

			<description><![CDATA[Three-dimensional (3D) video technology is becoming increasingly popular, as it can provide stereoscopic perception and immersive experience to end users. Some asymmetric stereoscopic video coding methods had been developed by utilizing binocular psycho-visual redundancy. However, rate control problem had not been well considered in these methods to further control the quality of stereoscopic video. In this paper, a novel rate control method is proposed for asymmetric-quality stereoscopic video. In order to model the asymmetric-quality stereoscopic video, we use a fixed threshold to quantize the binocular psycho-visual redundancy and establish the relationship between the distortion and quantization for the asymmetric-quality stereoscopic video. Then, a rate control method is engineered in stereoscopic video coding to control the rate and quality of left and right views. Experimental results show that the proposed method can accurately control the rate and quality of stereoscopic video, while having a lower computational complexity<sup>1</sup>.]]></description>

			<description><![CDATA[Due to the recent explosive growth of smart TV and its applications, the need for multimedia contents analysis techniques for smart TV environment has dramatically increased. In particular, automatic video annotation and summarization technique is considered as one of the most important technique for smart TV because an enormous number of social videos are now becoming available as well as traditional digital videos such as TV programs and VODs. In this paper, we present an automatic video annotation technique which employs the ontologies to facilitate the video retrieval and sharing process in smart TV environment. In our work, ontologies are exploited to hierarchically describe the contents of video and facilitate the sharing of video contents among heterogeneous users or devices (e.g., smart phone, PDA, and so on). Through various experimental results, we show the effectiveness of the proposed approach<sub>1</sub>.]]></description>

			<description><![CDATA[A low complexity weighted two-bit transforms (2BT) based multiple candidate motion estimation algorithm is proposed in this paper. By exploiting almost the identical operations in two different matching error criteria, we can efficiently determine two best motion vectors according to the respective matching criteria with negligible complexity increase. And with additional local square search, the proposed algorithm can enhance the overall motion estimation accuracy substantially. Experimental results show that the proposed algorithm achieves peak-to-peak signal-tonoise ratio (PSNR) gains about 0.55dB on average compared with the conventional 2BT-based motion estimation.<sup>1</sup>]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131162]]></link>
			<description><![CDATA[Video sensor based human activity recognition systems have potential applications in life care and health care areas. The paper presents a system for elderly care by recognizing six abnormal activities; forward fall, backward fall, chest pain, faint, vomit, and headache, selected from the daily life activities of elderly people. Privacy of elderly people is ensured by automatically extracting the binary silhouettes from video activities. Two problems are addressed in this research, which decrease recognition accuracy during the process of abnormal human activity recognition (HAR) system development. First, the problem of continuous changing distance of a moving person from two viewpoints is resolved by using the R-transform. R-transform extracts periodic, scale and translation invariant features from the sequences of activities. Second, the high similarities in postures of different activities is significantly improved by using the kernel discriminant analysis (KDA). KDA increases discrimination between different classes of activities by using non-linear technique. Hidden markov model (HMM) is used for training and recognition of activities. The system is evaluated against linear discriminant analysis (LDA) on the original silhouette features and LDA on the R-transform features. Average recognition rate of 95.8% proves the feasibility of the system for elderly care at home <sup>1</sup>.]]></description>

			<description><![CDATA[In order to improve the quality of the reconstructed video, the Wiener filter is employed in video coding to reduce the distortion caused by chrominance down/up sampling and encoding. Based on the mathematical analysis, it is verified that the distortion introduced by chrominance sampling and coding can be approximately treated as a wide sense stationary noise, which can be suppressed by the Wiener filter. Accordingly, in this paper, a two-dimensional Wiener filter is designed for reducing the noise of the reconstructed chrominance components, which further improves the video quality in the RGB color space as finally perceived by the users. Experimental results show that compared with bi-linear and inter-color up-sampling, the proposed method achieves the average gains of 0.42 dB and 0.30 dB, respectively. Meanwhile, the reconstructed video obtained by the proposed method is more close to the original one in terms of subjective quality<sup>1</sup>.]]></description>

			<description><![CDATA[Multiview video plus depth (MVD) is a new 3D video format that would support 3D applications developed by MPEG. Such a format is a combination of texture video and associated depth maps. Consequently, for the efficient transmission of 3D video signals, the compression of texture video and also the depth maps is required. Since high computational complexity of jointly coding between the texture video and depth map is still an open question, this paper introduces a low complexity MVD coding algorithm that adaptively utilizes the texture and depth map correlation. Based on the correlation, we propose four efficient techniques, including depth information based fast mode size decision, adaptive disparity estimation in texture coding, motion vector sharing based on the texture image similarity correlation and the SKIP mode decision in depth coding. Experimental results show that the proposed algorithm can significantly reduce the computational complexity of MVD coding while improve the coding performance and achieve better rendering quality<sup>1</sup>.]]></description>

			<description><![CDATA[The emerging High Efficiency Video Coding (HEVC) standard is expected to require much more processing power than its predecessors due to the higher algorithmic complexity of new coding tools and associated data structures. This paper proposes a novel complexity control method for the near future HEVC encoders running on power-constrained devices. The proposed method is based on a decision algorithm that dynamically adjusts the depth of the Coding Units (CU) defined by quad-tree structures. New evidence about the relationship between CU depth and coding complexity is used to selectively constrain the CU depth in order to not exceed a predefined complexity target. The experimental results show that the encoder computational complexity can be downscaled by up to 60% at the cost of negligible loss of rate-distortion (RD) performance. The proposed method finds application in the near future multimedia portable devices using HEVC codecs<sup>1</sup>.]]></description>

			<description><![CDATA[This paper presents a new image stitching algorithm for mobile multimedia devices. In general, the stitched image obtained by optimal seam finding can avoid the ghost effects but sometimes experience the unconformity of the image structure and color differences near the transition region between images. To solve these problems, the proposed algorithm adopts the seam carving/inserting operator and exploits an adaptive color blending algorithm. Experimental results show that the proposed algorithm can produce a stitched image without visible artifacts including the ghost effects, the unconformity of the structure, and the visible color differences. With respect to the visual quality of the stitched images, the proposed algorithm significantly outperforms simple conventional stitching algorithms and is comparable to the computationally demanding Poisson image editing algorithm<sup>1</sup>.]]></description>

			<description><![CDATA[In neuroscience and psychology, visual imagery is the subjective experience of seeing in the absence of visual stimulation. Someone may experience touch or sound as a result of visual imagery. In this paper, a new visual image aid which can provide a different way to visualize the image for visually impaired users is proposed. It is done by applying the depth image to an Image-To-Sound Mapping (ITSM) system. The proposed algorithm utilizes a sparse Census transform (SCT) and color segmentation to obtain an illuminationinvariant depth image. The depth image is applied to the ITSM system and then a clear and simple sound output is obtained for constructing a mental image. Moreover, the reliable three-dimensional (3D) data of close objects are extracted and interpreted as a semantic speech output. Experimental results show that visually impaired users can perceive the image easily and without training by adding verbal description to the visually image aid. In good and poor illuminated environments, the performance is 82% and 80% respectively. The performance of our proposed systems was not influenced by various lighting. All subjects also commented that the systems would be potentially useful<sup>1</sup>.]]></description>

			<description><![CDATA[This paper presents a proposal of a superrealistic environmental sound synthesizer for a location-based sound search system. The location-based sound search system enables a user to experience any environmental sound in any desired remote place. This synthesizer is achieved by spatial audio mixing considering real-world conditions such as geographical features and townscapes, as well as dynamic situations such as those of town events and weather. Furthermore, a new velocity vector-based clustering method is proposed to reduce the cost of audio processing on the server side, which achieves a lower number of composing and decomposing clusters that have a direct and strong impact on high-cost audio processing such as spatial audio mixing<sup>1</sup>.]]></description>

This is already done for the DTV receivers but the MPEG decoders are still subject to improvement. Since audio errors are perceived as being much more annoying than video errors, this paper focuses on the adaptations of the audio signal processing. An evaluation of the influence of mobile transmission errors on the audio processing is presented and adaptations are proposed. We show that the amount of correctly decoded frames can be increased by up to 5 % whereas the amount of incorrectly decoded frames can be decreased by up to 16 %. Both will result in an improvement of the perceived audio quality<sup>1</sup>.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131171]]></link>
			<description><![CDATA[In this paper, a virtual elevation method of a sound source is proposed for a stereo loudspeaker reproduction. To achieve this goal, the proposed method first applies a head-related transfer function (HRTF) to the sound source to vertically localize it. Then, spectral notch filtering followed by directional band boosting is used for the further elevation of the sound source. In particular, a filter having three notches is designed by analyzing the spectral characteristics estimated from the measured HRTF database and by investigating the effect of spectral boosting on the perception of sound elevation. To evaluate the elevation performance of the proposed method, subjective listening tests are subsequently conducted using several sound sources, including male and female speech, as well as guitar, violin, and pop music. It is shown from the tests that the sound sources processed by the proposed method are most likely to be perceived as if they are played from stereo loudspeakers located at around 20&#x000B0;, even though the stereo loudspeakers are actually located on a horizontal plane, i.e., 0<sup>??.1</sup>]]></description>

			<description><![CDATA[Spatial and temporal scalability in Scalable Video Coding (SVC) compression enables a video encoder to generate bit streams efficiently for various resolutions and frame rates. However, doing this requires more complex computations and greater memory bandwidth than H.264/AVC compression. In this paper, the performance and memory bandwidth for a SVC hardware encoder with three spatial and temporal layers are analyzed. Based on the analysis, a novel method is proposed for the source and interlayer data load. Experimental results show that the memory bandwidth is reduced by 77%. Furthermore, the memory access latency of the source data for the base layer is reduced by creating a data load for the base layer overlap with the execution of the enhancement layer. To satisfy the latency requirement, a mode pre-decision algorithm for a hardware SVC encoder is proposed. It reduces the computation of the fractional motion estimation (FME) and the inter-layer residual prediction by 80%. Simulation results show that the proposed methods decrease the BD-PSNR by 0.05 dB and increase the BD-BR by 1.64%, an amount that can be considered negligible in terms of degradation, while an encoding speed of 30 fps for Full HD (1920??1080) videos is achieved at an operating clock frequency of less than 200 MHz.<sup>1</sup>]]></description>

			<description><![CDATA[Disparity acquisition is beneficial to various 3D multimedia applications, i.e., free viewpoint TV (FTV), 3DTV, and 3D scene model reconstruction. In this paper, we propose an efficient disparity map estimation method with occlusion handling taken into account. In order to detect occlusion, we obtain left and right initial disparity maps via optimization based on modified constant-space belief propagation, a low complexity algorithm. The initial disparity maps provide clues for occlusion detection. From the clues, an energy function is defined and optimized by energy minimization framework. We define two occlusion types and apply suitable occlusion handling processes, accordingly. The proposed occlusion handling method extends disparity values of visible pixels to occluded pixels. Experimental results show that our method provides near-ground truth occlusion and a superior disparity map compared to other stateof- the-art methods with occlusion handling. Our contribution provides solid advantages regarding disparity map estimation, which is useful for various 3D multimedia applications.]]></description>

			<description><![CDATA[Many mobile devices compress images excessively to meet limited bandwidth requirements and adopt the Block-based Discrete Cosine Transform (BDCT) coding structure. This produces inevitably the visually annoying noises including blocking artifacts in the decoded images. We present a Signal Adaptive Weighted Sum (SAWS) technique of block boundary pixels to alleviate the blocking artifacts encountered in highly compressed images. The weights are adjusted adaptively according to the directional correlation and activities of local areas. To avoid blurring the original details, we employ a parameter that can control the strength of deblocking. Comprehensive experiments demonstrate that the proposed approach achieves excellent visual quality and PSNR compared to a number of deblocking methods in the literature. Moreover, the low complexity of the proposed algorithm facilitates the application to mobile devices.]]></description>

			<title><![CDATA[An efficient re-coloring method with information preserving for the color-blind]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131176]]></link>
			<description><![CDATA[In this paper, a fast re-coloring method with information preserving is proposed for the color-blind (CB) who experiences difficulty to discriminate some color differences. In the proposed algorithm, we utilize a new color transform that can enhance the perceptibility for the CB while maintaining the re-colored image as natural as possible for the normal viewer. In addition, an improved method which effectively detects the CB unperceivable (CBU) colors to be re-colored is introduced. Experimental results show that the proposed method can produce more comprehensible images for CB viewers while preserving the naturalness of the recolored images for standard viewers with reduced complexity.]]></description>

			<title><![CDATA[Real-time panorama canvas of natural images]]></title>
			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131177]]></link>
			<description><![CDATA[This paper deals with a real-time panorama algorithm for mobile camera systems. The proposed system generates the panoramic images and shows the intermediate results simultaneously on the mobile display. The proposed panorama system consists of feature point extraction, feature tracking, rotation matrix estimation, and image warping onto cylindrical surface. Feature points are extracted by fast Hessian detector in the low resolution and corner detector in the high resolution. Then, the feature points are tracked by matching between input frame and synthesized panorama image. The camera motion is modeled as a rotation matrix which is estimated using the tracked feature points. For realtime operation of panoramic image synthesis, we propose a method to estimate the rotation matrix using non-iterative least square method. We project the feature points of image onto the unit sphere surface in the world coordinates. This enables us to estimate the parameters of rotation matrix as the linear and non-iterative problem. Finally, we project the input frames onto panorama surface using the rotation matrix. We also implement a real-time display interface to show the intermediate panorama results while panorama image is being generated. Thus, the proposed panorama system paints the panorama canvas with real images. According to the experiments in the mobile systems such as mobile phone and tablet PC, the proposed system works well to generate the panoramic images in real-time.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131178]]></link>
			<description><![CDATA[Consumer electronic products are increasingly becoming more open and flexible, which is achieved by replacing dedicate, single-function hardware components by software components running on programmable platforms. Scalable video algorithms (SVAs) using the novel principle of priority processing can guarantee real-time performance on these platforms even with limited resources. In this paper we describe the mapping of a priority-processing application on an embedded consumer platform comprising a general purpose processor and multiple stream processing elements. An application comprises one or more independent, competing priority-processing algorithms. These SVAs have a single, dedicated streaming processor at their disposal. Dynamic resource allocation is required to maximize the overall output quality of SVAs that are executed on a shared platform. To enable real-time processing of individual SVAs, we compare the performance of different implementations for dynamic-resource-allocation mechanisms. Finally, we show that priority processing achieves real-time performance even under tight resource constraints.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6131104&arnumber=6131179]]></link>
			<description><![CDATA[With the promising development of user assist services on consumer electronics portable devices, service applications must continuously monitor dynamically changeable data and status, and judge whether their service actions should be activated. These operations, performed in real-time, result in heavy resource consumption on the portable devices. This paper proposes an innovative way to reduce the consumption by aggregating data access timings requested from multiple applications. Simulation shows that the proposed method can provide the highest precision data while reducing resource consumption. This mechanism can be installed into an operation system on a mobile device, or can operate as a middleware on the device. This must be one of key technologies to reduce battery power consumption of CE devices.]]></description>
