Abstract :
This paper describes a texture model application for future video compression algorithms. This employs region-based texture analysis techniques and advanced motion models to synthesise and warp video frames rather than encode the whole image or the prediction residual after traditional motion compensation. The proposed texture warping method and the dynamic texture model are integrated into an H.264 framework together with video quality assessment modules to prevent video artefacts. The results show impressive bitrate savings, up to 47%, over H.264 with similar visual quality.
