Very low bit rate video coding using active triangular mesh

This paper presents a video coding scheme for very low bit rate applications. The coding approach relies on the notion of active meshes and can be viewed as a particular case of region-based coding. The active mesh is used to efficiently represent and code the various regions of the scene as well as the motion information. The algorithm involves the following steps: projection (time tracking of the regions); partition and motion coding; synthesis; modification of the mesh topology (introduction of new regions and elimination of useless regions); and texture coding
