2-DIMENSIONAL MESH-BASED VISUAL-OBJECT REPRESENTATION FOR INTERACTIVESYNTHETIC NATURAL DIGITAL VIDEO/

This paper first provides an overview of two-dimensional (2-D) and thr ee-dimensional mesh models for digital video processing. It then intro duces 2-D mesh-based modeling of video objects as a compact representa tion of motion and shape for interactive, synthetic/natural video mani pulation, compression, and indexing. The 2-D mesh representation and t he mesh geometry and motion compression have recently been included in the visual tools of rite upcoming MPEG-4 standard. Functionalities en abled by 2-D mesh-based visual object representation include animation of still texture maps, transfiguration of video overlays video morphi ng, and shape-and motion-based retrieval of video objects.
