Abstract
Recent developments in the compression of dynamic meshes or mesh sequences have shown that the statistical dependen-cies within a mesh sequence can be exploited well by predic-tive coding approaches. Coders introduced so far use ex-perimentally determined or heuristic thresholds for tuning the algorithms. In video coding rate-distortion (RD) optimi-zation is often used to avoid fixing of thresholds and to se-lect a coding mode. We applied these ideas and present here an RD-optimized mesh coder. It includes different predic-tion modes as well as an RD cost computation that controls the mode selection across all possible spatial partitions of a mesh to find the clustering structure together with the asso-ciated prediction modes. The structure of the RD-optimized D3DMC coder is presented, followed by comparative results with mesh sequences at different resolutions. 1.
