Abstract
This paper presents a video coding scheme combining H264 with a triangular mesh based representation. In this scheme, we developed a mesh-based motion estimator in which the motion vectors are computed at each node of the mesh. All other motion vectors are then interpolated using the nodes denoting the patches. Finally, this model is integrated in the RD optimized model of the H264 coder. To end, we propose some results, which compare H264 with our hybrid approach. This approach permits us to improve the quality of P and B images obtained by H264 for the same coding cost.
