Abstract : Abstract-This paper proposes a novel prediction tool for improving the compression performance of texture atlases. Our algorithm takes advantage of the topology of the associated 3D meshes, in order to reduce the redundancies in the texture map. The concept of intra prediction used in video compression has been adapted to consider neighboring information on the 3D surface. We have then combined this prediction tool with an original block scanning strategy and a graph-based transform for residual coding. Results show that the knowledge of the mesh topology significantly improves the compression efficiency of texture atlases.
