Abstract
The invention relates to motion estimation and compensation between two given images represented by a polygonal mesh. It provides a solution to the problems of crowding and uncovering of mesh units when the mesh is shifted. More specifically, the invention relates to a method for the encoding of a mesh that represents an image of a moving sequence. According to the invention, such a mesh is larger in size than the image.
