摘要：
In this paper, a pure geometry compression algorithm for 3D semi-regular meshes, based on wavelet transform and space frequency quantization for 3D meshes, has been introduced. The local frame was applied to wavelet coefficients to be more independent, and the 3D SFQ was used to quantize the coefficients. The proposed algorithm was compared with the zero-tree coder for MAPS meshes. The rate-distortion curves results are significantly better than those for zero-tree coder in the high rates.
