Abstract

In this paper a hierarchical spatial scalable wavelet video coder is presented. The scheme employs backward motion compensation, therefore no motion vectors have to be transmitted. The coarser levels of the wavelet decomposition of the current frame are used for motion estimation and motion compensation of the lowpass band of the next finer level. The lowpass band of the coarsest level has to be coded separately, e.g. using DPCM.
