Methods for object-based compression and composition of natural and synthetic video content are currently emerging in standards such as MPEG-4 and VRML. This paper describes novel techniques for compression of 2-D triangular mesh geometry and motion, enabling efficient representation and manipulation of video content. Specifically, mesh geometry is compressed by predictive coding of mesh node locations. Mesh node motion vectors are compressed by predictive techniques as well. Preliminary results show that the mesh data can be coded at a fraction of the bits used to code a typical video object
