摘要
本文提出了一种二次曲面逼近图象编码的四叉树实现方案根据对二次曲面逼近图象编码算法和图象的局部统计特性的分析，编码质量和图象方块的平坦程度及大小有关，因此，可按照对编码质量的要求。
A quadtree scheme for second order curved surface approximation image coding is presented. According to theoretical analysis to the algorithm and that of the image local statistics, the coding quality is related to the smoothness and the size of the block. Therefor, variable block size can be chosen with a quadtree structure based on the quality requirement. Experiment results show that the scheme is correct.
