Abstract

In this paper a method for very low bit rate coding of video sequences is described. The method is based on spatio-temporal segmentation of the sequence into semantically significant regions with polygonal shapes. The motion parameters, structural description of regions and reconstruction by motion compensation error should be encoded to reconstruct high quality images at the decoder. In the coding scheme, the temporal coherence of the regions structure and of motion compensation error are taken into account in the encoding scheme to achieve a very low bit rate.
