LAR Video: Hierarchical Representation for Low Bit-Rate Color Image Sequence Coding

Abstract

LAR video is a low complexity system for low bit-rate color image sequence encoding. It aims to propose a joint solution for coding and representation of the frame content. In particular, it allows to provide a compressed description of both chromatic components and motion information at a region level without region partition encoding. Initialy proposed in the LAR coder, used principle has proved to be efficient for still color image encoding. Resulting from a hierarchical spatio-temporal segmentation, a Partition Tree (PT) is transmitted to the decoder with a controlled coding cost. Presented results show interesting performances considering both content representation and compression ratios.
