    JPEG2000 is an upcoming compression standard for still images that has a feature set well tuned for diverse data dissemination. These features are possible due to adaptation of the discrete wavelet transform, intra-subband bit-plane coding, and binary arithmetic coding in the standard. We propose a system-level architecture capable of encoding and decoding the JPEG2000 core algorithm that has been... View full abstract»

    This paper proposes a quality-of-service (QoS)-adaptive proxy-caching scheme for multimedia streaming over the Internet. Considering the heterogeneous network conditions and media characteristics, we present an end-to-end caching architecture for multimedia streaming. First, a media-characteristic-weighted replacement policy is proposed to improve the cache hit ratio of mixed media including conti... View full abstract»

  • Analysis and architecture design of block-coding engine for EBCOT in JPEG 2000

    Embedded block coding with optimized truncation (EBCOT) is the most important technology in the latest image-coding standard, JPEG 2000. The hardware design of the block-coding engine in EBCOT is critical because the operations are bit-level processing and occupy more than half of the computation time of the whole compression process. A general purpose processor (GPP) is, therefore, very inefficie... View full abstract»

  • Color quantization of compressed video sequences

    This paper presents a novel color quantization algorithm for compressed video data. The proposed algorithm extracts discrete cosine (DC) transform coefficients and motion vectors of blocks in a shot to estimate a cumulative color histogram of the shot and, based on the estimated histogram, design a color palette for displaying the video sequence in the shot. It significantly reduces the complexity... View full abstract»

  • Vector SPIHT for embedded wavelet video and image coding

    The set partitioning in hierarchical trees (SPIHT) approach for still-image compression proposed by Said and Pearlman (1996) is one of the most efficient embedded monochrome image compression schemes known to date. The algorithm relies on a very efficient scanning and bit-allocation scheme for quantizing the coefficients obtained by a wavelet decomposition of an image. In this paper, we adopt this...

  • An efficient low-cost antialiasing method based on adaptive postfiltering

    Aliasing in computer-synthesized images not only limits the realism of the images, but also affects the user's concentration. Many antialiasing methods have been proposed to solve this problem, but almost all of them are computation intensive, and some of them are also memory intensive. While these may not be limitations for high-end applications such as medical visualization and architectural des... View full abstract»

  • Design and implementation of a fuzzy hardware structure for morphological color image processing

    A hardware implementation of a fuzzy processor suitable for morphological color image processing applications is presented for the first time. From the hardware point of view, only a small number of algorithms for hardware implementation of soft gray-scale morphological filters have been reported in the literature, since research in mathematical morphology focuses mainly on possible extensions of ...
