Abstract :
In this paper we present an image sequence coding scheme for very low bit rate coding which is based on spatial redundancy reduction via the new edge sensitive subband coding method and temporal redundancy reduction via windowed overlapped block-matching motion compensation. The scheme has the main advantage, that only the significant regions of difference-images are coded. Thus the computational cost can be kept low. Due to the properties of both the temporal and the spatial coding used, there are no blocking effects in the coded images, and the overall visual performance of the coding scheme is very good
