We present in this paper an original approach to encode the geometry of animated sequences of meshes (with a fixed connectivity). The main contribution is the use of a temporal lifting scheme to exploit the high temporal coherence in the geometry of successive frames. The sequences of wavelet coefficients are then encoded by an efficient coding scheme that includes a bit allocation optimizing the quantization process. Simulation results show that the proposed algorithm provides better compression performances than some state of the art coders.
