    Progressive image transmission (PIT) is widely used in many applications, since it generates the successively improved reconstructions of an image. In spatial domain PIT systems, perfectly reconstructed images can be obtained at the final stage. However the intermediate images are not good and there is no data compression. In this paper, the authors present a new simple spatial domain progressive ... View full abstract»

    A new recursive block-matching motion estimation algorithm with only eight candidate vectors per block is presented. A fast convergence and a high accuracy, also in the vicinity of discontinuities in the velocity plane, was realized with such new techniques as bidirectional convergence and convergence accelerators. A new search strategy, asynchronous cyclic search, which allows a highly efficient ... View full abstract»

  • A DCT-based aliasing cancellation method in subband coding

    Aliasing artifacts of subband coded pictures at low bitrates can be eliminated by adding the information from the higher bands that cancel aliasing at the lower band. This is done by DCT coding the high-frequency bands and selecting the coefficients with the highest energy. The optimum scanning directions of these coefficients for each band are given. As an application of these ideas, a method for... View full abstract»

  • Multistage sampling structure conversion of video signals

    The work extends multistage implementation of sampling structure conversion to the multidimensional (M-D) case. The issues arising in this task are usefully addressed on the basis of lattice theory. Numerical data supporting the advantages of multistage sampling conversion are presented, and the case of format conversion from the 4/3 to the 16/9 aspect ratio is examined as a study case. The main i... View full abstract»

  • Image compression using finite-state vector quantization with derailment compensation

    Presents an image compression method using a finite-state vector quantizer (FSVQ) with derailment compensation. The derailment problem in conventional FSVQ systems is discussed first. Then a novel scheme is presented to overcome the problem. In this scheme, each state is partitioned into K Voronoi regions. The corresponding region codebook is designed individually. A simple initial classifier base... View full abstract»

    The paper describes a differential-vector-quantization (DVQ) algorithm that has been developed for realtime compression of digital video images. The authors discuss a number of experiments performed to insure that the algorithm is suitable for hardware implementation. They show that the DVQ algorithm performs comparably to scalar differential-pulsecode-modulation (DPCM) methods in terms of image q... View full abstract»
