Temporal wavelet-based compression of 3D animated meshes using motion-based clustering
Résumé
This paper presents an efficient compression algorithm to encode the geometry of 3D mesh sequences with fixed connectivity. The proposed approach includes a temporal scan-based wavelet transform and motion compensation of the mesh geometry. Motion estimation/compensation is performed thanks to an efficient motion-based clustering approach The motion parameters are modeled by affine transforms matrix which are coded losslessly using arithmetic coding. Simulation results show that the proposed method provides good compression performances.
