1. ABSTRACT With fast computation and excellent compression efficiency, two embedded coding techniques, zero-tree/-block coding and context modeling of the subband/wavelet coefficients, have been widely utilized for image coding applications. In this research, we present a new embedded wavelet image coding algorithm with an attempt to combine advantages of(More)
Three-dimensional subband coding with motion compensation MC-3DSBC has been demonstrated 1144 to be an eecient technique for video coding applications. With half-pixel-accurate motion compensation, images need to be interpolated for motion-compensated MC temporal ltering. The resulting analysisssynthesis system is not invertible. In this paper, we propose a(More)
This paper develops a new intra-frame dyadic spatial scalable coding framework based on a subband/wavelet coding approach for MPEG-4 AVC/H.264 scalable video coding (SVC). It is the first attempt in the literature to join the subband filter banks with the traditional macroblock and DCT based video coding system. We demonstrate that the current H.264 coding(More)
Three-dimensional (3-D) subband/wavelet coding with motion compensation has been demonstrated to be an efficient technique for video coding applications in some recent research works. When motion compensation is performed with half-pixel accuracy, images need to be interpolated in both temporal subband analysis and synthesis stages. The resulting subband(More)
Part 7 of MPEG-21 entitled digital item adaptation (DIA), is an emerging metadata standard defining protocols and descriptions enabling content adaptation for a wide variety of networks and terminals, with emphasis on format-independent mechanisms. The DIA descriptions provide a standardized interface not only to a variety of format-specific adaptation(More)
