SCALABLE CONTEXT-BASED MOTION VECTOR CODING FOR VIDEO COMPRESSION
Valéry Valentin, Marco Cagnazzo, Marc Antonini, Michel Barlaud · 2003
State of the art video compression algorithms use motion compensation. Using such method gives better results by increasing the temporal correlation between pixels from consecutive frames. Most of the effort in increasing the performance of existing algorithms concentrates on the improvement of motion vector uses and residual coding. In this paper we propose a motion vectors computation and coding scheme for video compression which combines constrained block matching and scalable coding based on a threestep search-like decomposition.
