Octave subband coding has been used as an efficient image coding approach for various well-known standards such as MPEG-4 and JPEG-2000. Although the sub-images in the octave subband representation have low statistical correlation, the visual similar

If the same digital television signal is used for multiple resolutions, bit rates, or transmission and storage mechanisms, then hierarchical coding offers several advantages. The FCC has decided to adopt the "main profile" of MPEG-2 for the video rep

We present a technique to improve the speed of block motion estimation using only a subset of pixels from a block to evaluate the distortion with minimal loss of coding efficiency. To select such a subset we use a special sub-sampling structure, N-qu

MPEC-4 VTC provides coding efficiency using the zerotree entropy coding (ZTC) to remove the statistical redundancy among the coefficients within each wavelet tree. To improve the coding efficiency of ZTC, we propose an MPEG-4 compliant perceptual dit

A two-layer coding approach with spatial pyramid to achieve compatibility [1] has been known to have several advantages. The first layer can have optimal performance, as it is done independently. Rate control can be distributed between layers. Howeve
