24 October 2005Robust compression and reconstruction of 3-D mesh data
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.
