    Block artifact is a serious problem which generally emerges in video or image compression system based on block. In H.264, strength, a value which indicates the degree of block artifact, is obtained by the prediction mode, reference frames and motion vectors. However, in some cases, the de-blocking method in H.264 is not so satisfactory because of the ignorance of image behavior. According to the ... View full abstract»

    In this paper, a novel approach to impulsive noise detection is proposed for colour image restoration. First, a global adaptive region growing scheme is used to separate uncorrupted clusters of pixels from corrupted clusters. Then, some order statistic vector filters are used to reconstruct the corrupted clusters. Various performance analyses show the detection scheme is more robust for a wide ran... View full abstract»

    The traditional SRR (super-resolution reconstruction) estimations are based on L1 or L2 statistical norm estimation therefore these SRR methods are usually very sensitive to their assumed model of data and noise that limits their utility. This paper reviews some of these SRR methods and addresses their shortcomings. We propose a novel SRR approach based on the stochastic regularization technique o... View full abstract»

    The restoration of video signals corrupted by the additive noise is important for getting the high quality video and the high compression ratio of video signals. In this paper, we propose a novel restoration method for video signals corrupted by the Gaussian noise. Conventional methods use the spatio-temporal filtering after the motion compensation. However, the accuracy of the motion compensation... View full abstract»

    Three-dimensional (3D) urban models, come with huge data size, mainly consisting of the information of geometry and the texture, and the simplification of both is often needed for efficient streaming, rendering and visualization. In this paper, we present different techniques for simplification of different types of the texture images in 3D urban maps, aiming at their visualization on low resoluti... View full abstract»

    A method for estimating why a baby is crying is proposed using frequency analyses of the voice. In this paper, three causes, hunger, sleepiness and discomfort, are considered for classification. Moreover, the method intends for younger babies aged from 2 to 4 months old. Some typical characteristics are obtained for hunger, sleepiness, and discomfort, respectively, in the shape of the power spectr... View full abstract»

    Recently, speech, especially word recognition using visual information, has attracted significantly interest. In word recognition, the target is not just a word, but also a vowel. However, since vowel frames do not contain many phonemes, vowel recognition rate is less than that of the word. Some research has been done on vowel recognition. This paper analyses features that can effectively recogniz... View full abstract»

    This paper produces two types of the features of speaker recognition, mean of column elements (MC) and squared 2-norm of column elements (SNC). Both of them are derived from the curvelets representing the geometrical structure of squared modulus of Gabor representation of one-dimensional speech. The performance evaluation experiments have been conducted and the results indicate that with the score... View full abstract»

  • Study of Relationships between Intra-speaker's Speech Variability and Speech Recognition Performance

    Even if a speaker uses a speaker-dependent speech recognition system, speech recognition performance varies. For this reason, speech quality is varied by some factors, including emotion, background noise, and so on, even though the speaker and utterance remain constant. However, the relationships between intra-speaker's speech variability and speech recognition performance are not clear. Hence, we... View full abstract»

    In this paper, we report implemental results of an embedded version of Julius. We used T-Enginetrade as a hardware platform which has a SuperH microprocessor. The Julius is free and open continuous speech recognition (CSR) software running on personal computers (PCs) which have huge CPU power and storage memory size. The technical problems to make Julius for embedded version are computing/process ... View full abstract»

    This paper investigates the dynamic spectrum management (DSM) problem in mixed asymmetric digital subscriber line (ADSL) CO/RT deployments. A new distributed DSM algorithm is developed with an objective of enlarging the achievable rate region. The results show that the new algorithm achieves significant performance gains over the existing distributed DSM algorithm iterative water-filling (IW). Sim... View full abstract»

    Ad-hoc network is an autonomous network that consists of only mobile terminals without an infrastructure such as base stations. The wireless LAN system with IEEE 802.11 standard is one of the candidate schemes to realize ad-hoc network. In IEEE 802.11, CSMA/CA (carrier sense multiple access with collision avoidance) is used as access control method. Moreover RTS/CTS (request to send/clear to send)... View full abstract»
