摘要
基于一种人头三维表面数据压缩算法，分析其算法原理上的不足并加以改进．在新算法中利用了人头细节特征的先验知识，在优先保证经线压缩数据完整性的前提下，对三维数据集进行采样，达到良好的重建效果．
A method of 3 D data compression of the human head is analyzed and an
algorithm presented. Transcendental knowledge of detailed character of human head is applied to
the new algorithm. On the basis of keeping the integrality of latitude cruve and taking the statistical
information of neighbor curves into account, we have re sampled the 3 D data set and gooten
satisfactory reconstructing effect of detail zones.
