Progressive encoding of voxel surfaces based on pattern code representation

We propose a progressive encoding algorithm for 3D voxel surfaces, based on the pattern code representation (PCR). In PCR, a voxel surface is represented by a series of pattern codes. It can achieve coding gain, since the pattern codes are highly correlated. In the multi-resolution framework, the coding gain can be further improved by the decimation constraint from the lower resolution surface. Furthermore, an alternative patternbook is adopted for voxels within smooth regions to reduce the number of possible pattern codes. Simulation results show that the proposed algorithm provides better performance than the conventional PCR algorithm.
