Abstract (en)

[origin: WO0207099A1] The invention concerns motion estimation and compensation between two given images, represented by a polygonal mesh, and provides a solution to mesh crowding and unmasking when the mesh is moved. More precisely, the invention concerns a method for coding a mesh representing an animated sequence image. Such a mesh is larger in size than said image.
