    The Motion Picture Experts Group (MPEG) video-coding algorithm is regarded as a promising coding algorithm for coding full-motion video. However, since MPEG was originally designed for storage applications, some problems must be solved before the algorithm can be applied to interactive services. Due to the use of periodic intraframe coding and bidirectional interframe prediction, the end-to end de... View full abstract»

    The application of transform coding using trellis coded quantization (TCQ) to encode monochrome and color images is investigated. Specifically, TCQ is used to encode transform coefficients resulting from applying a 16 * 16 discrete cosine transform (DCT) to 8-b gray level and 24-b color images. For the color images, the red, green, and blue (RGB) planes are transformed into the NTSC transmission p... View full abstract»

    The authors propose a novel adaptive spatiotemporal filter, called the adaptive weighted averaging (AWA) filter, for effective noise suppression in image sequences without introducing visually disturbing blurring artifacts. Filtering is performed by computing the weighted average of image values within a spatiotemporal support along the estimated motion trajectory at each pixel. The weights are de...

    Visual pattern image sequence coding (VPISC) is a new digital image sequence (video) coding process that possesses significant advantages relative to other technologies; in particular, it is extremely efficient in terms of the computational effort required. It is designed to exploit properties of the human visual system (HVS), and thus yields high visual fidelity. Visual quality criteria are delib... View full abstract»

  • A VLSI chip set for DPCM coding of HDTV signals

    Publication Year: 1993, Page(s):302 - 308
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (919 KB)

    For digital HDTV studio-to-studio transmission at 565 Mb/s the hardware implementation of a differential pulse code modulation (DPCM) coding algorithm with 2-D prediction and a fixed code word length is reported. The data rate is reduced by a factor of about two. Noise shaping improves the picture quality of both luminance and chrominance. Parallel processing, a modified DPCM structure, and pipeli...

  • On the determination of all the sublattices of preassigned index and its application to multidimensional subsampling

    Subsampling offers an effective and simple way to implement a data compression technique. Its use in the video context is rather attractive, as its application to current video broadcasting schemes, such as MUSE and HD-MAC, clearly shows. A sensible exploitation of subsampling's potential requires the systematic evaluation of the image degradation effects due to the specific subsampling lattice. S... View full abstract»

    Vector quantization (VQ) has become feasible to be employed for real-time applications by using VLSI technology. In this paper, the authors propose modular linearly connected VLSI architectures for VQ that can support real-time image processing applications. Each processing element in the design consists of an adder and a shift register instead of a multiplier. The designs require fixed I/O bandwi... View full abstract»

    The authors develop a technique to compress HDTV images to below 135 Mb/s at transparent quality, i.e., visually indistinguishable from the original. This is at least equal to the contribution quality. The proposed scheme consists of a lossy and a lossless coder. The lossy coder combines the advantages of two image coding methods, namely, mean/residue vector quantization (MRVQ) and discrete cosine... View full abstract»
