静止图像的分形编码方法的改进

Modified Fractal Coding of Still Image

介绍一种使用迭代函数系统对静止图像进行编码的方法.该算法是利用一种自适应四叉树分段对局部图像特性进行分块.与已存在的分形编码方法相比,该算法能取得比较好的重构图像质量.

This paper introduces a method for still image using the theory of iterated function systems. The proposed algorithm accounts for the local image characteristics by an adaptive quadtree segmentation. In contrast to existing facial coding, a good reconstruction quality is achieved.
