  • Adaptive Image Interpolation Using Weight CVQ

    Publication Year: 2006, Page(s):3 - 10

    We propose a novel adaptive image interpolation method based on the weight classified vector quantization (CVQ) using optimal coefficients which are constrained by a quadratic signal class. It overcomes the computational complexity bottleneck of other second-order image interpolation methods such as an edge-directed and an optimal recovery interpolation. Our proposed interpolation method consists ... View full abstract»

  • DCT-Based Image Codec Embedded Cubic Spline Interpolation with Optimal Quantization

    Publication Year: 2006, Page(s):11 - 15
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (641 KB) | HTML iconHTML

    This paper proposes an improved DCT-based image codec embedded cubic spline interpolation (CSI) with optimal quantization. It is shown in literature that CSI is superior in performance to the other interpolation functions. One of main applications of the CSI is to cooperate with standard DCT-based JPEG to obtain the modified JPEG codec and still obtain a better quality of the reconstructed image f...

  • Digital Camera Resolution: An Improved Heisenberg-Gabor Testing Method

    Publication Year: 2006, Page(s):16 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4287 KB) | HTML iconHTML

    The paper demonstrates a method of simultaneously testing the spatial and tonal resolution of a camera. Unlike the modulation transfer function which has been used in the past, the measure proposed rates the resolution as a single number rather than a response over varied resolution, simplifying the measure and making it possible to compare the performance of different cameras easily. Previous wor... View full abstract»

  • Constant-Quality Rate Control Algorithm for Multiple Encoders with Single Video Source

    In this paper, we develop a constant-quality rate control algorithm for a surveillance system that consists of one "base encoder" for encoding a down-sampled full-view version of the input video sequence and one "region of interest (ROI) encoder" for encoding the region of interest of the input video at the original resolution. Exploiting the inter-relationship between these two independent encode... View full abstract»

  • Efficient Motion Estimation Using a Sorting-Based Early Termination Algorithm in H.264 Video Coding

    Publication Year: 2006, Page(s):31 - 36
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (595 KB) | HTML iconHTML

    The H.264/AVC video coding standard uses 7 variable block sizes ranging from 16times16 to 4times4 in interframe coding. The motion estimation with 7 modes needs very high computational complexity. To reduce the complexity of ME module in H.264, we propose a new and fast motion-estimation algorithm based on partial block distortion for sorted significant features including bit-plane and absolute di...

  • Accelerating Color Space Conversion Using Extended Subwords and the Matrix Register File

    Color space conversion is an important kernel in multimedia codecs such as JPEG and MPEG. When implemented using SIMD instructions, however, the performance improvement is often limited due to two reasons. First, corresponding color space components are stored at non-unit strides and, second, intermediate results can be larger than 8 bits. In this paper we show that extended subwords and the matri...

  • Affinity Hybrid Tree: An Indexing Technique for Content-Based Image Retrieval in Multimedia Databases

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (204 KB) | HTML iconHTML

    A novel indexing and access method, called affinity hybrid tree (AH-tree), is proposed to organize large image data sets efficiently and to support popular image access mechanisms like content-based image retrieval (CBIR) by embedding the high-level semantic image-relationship in the access mechanism as it is. AH-tree combines space-based and distance-based indexing techniques to form a hybrid str... View full abstract»

  • Annotating Image Regions Using Spatial Context

    Image annotation plays an important role in bridging the semantic gap between low level features and high level semantic contents in image access. In this paper, such a task is tackled by annotating regions which are primitives of a visual scene. We propose a probabilistic model to characterize spatial context for region annotation. Such a model provides a unifying framework integrating both featu... View full abstract»

    Automatic image content annotation techniques attempt to explore structural visual features of images that describe image content and associate them with image semantics. In this paper, two types of concept spaces, atomic concept and collective concept spaces, are defined and the annotation problems in those spaces are formulated as feature classification and Bayesian inference, respectively. A sc... View full abstract»

    In this paper, an interactive object annotation approach for video database will be proposed. The same semantic objects such as characters, backgrounds, and the main subjects in keyframes of each video shots can be queried and annotated based on the similarity of low-level features such as the color, area, and position of each region. An adaptive image enhancement algorithm is used for handling th... View full abstract»

    Retrieving information about the occurrences of persons in a video is an important task in many video indexing and retrieval applications. The problem is to answer the question "In which shots and scenes does person X appear?". In this paper, we present an automatic video annotation system with respect to a person's appearance based on state-of-the-art algorithms for face detection, tracking and r... View full abstract»

    Energy reduction is critical to increase the mobility and battery life for today's pervasive portable computing systems. At the same time, energy reduction must be subject to the real-time constraints and quality of service (QoS) requirements for multimedia applications running on many of these systems. This paper presents a novel run-time scheduling approach to reduce the system-wide energy consu... View full abstract»

    With the advances of compression technology, storage devices and networks, video on demand (VoD) service is becoming popular. The system needs to provide continuous service and heterogeneous service levels for users. However, these requirements cannot be satisfied in conventional VoD system which is constructed on redundant content servers and centralized management. In this paper, autonomous VoD ...
