Abstract

This paper presents an efficient mesh coding technique suitable for MPEG-4 video applications. The proposed technique significantly reduces the number of bits that are used to describe the mesh topology. It uses an adaptive structured mesh from coarse to fine, which can be coded as a count of splitting instead of nodes´ locations. In the case of the quadtree, less than one bit per node can be achieved. This reduction induces an improvement of either the image quality or the global bit rate
