Abstract

An algorithm for robust transmission of compressed 3-D mesh data is proposed in this work. In the encoder, we partition a 3-D mesh adaptively according to the surface complexity, and then encode each partition separately to reduce the error propagation effect. To encode joint boundaries compactly, we propose a boundary edge collapse rule, which also enables the decoder to zip partitions seamlessly. In the decoder, an error concealment scheme is employed to improve the visual quality of corrupted partitions. The concealment algorithm utilizes the information in neighboring partitions and reconstructs the lost surface based on the semi-regular connectivity reconstruction and the polynomial interpolation. Simulation results demonstrate that the proposed algorithm provides a good rendering quality even in severe error conditions.
