Error resilient coding of 3D meshes

Compressed bit streams of 3D mesh data are highly vulnerable to transmission errors due to predictive coding and entropy coding. In this work, we propose an error resilient and progressive coding scheme for 3D meshes. To make a compressed bit stream robust to transmission errors, 3D mesh data is partitioned into several segments, which are then encoded independently. In the decoder, a novel error concealment scheme is employed to improve the visual quality of corrupted segments. Simulation results show that the proposed algorithm provides a good quality reconstruction even in severe error conditions.
