摘　　要：以迭代函数系统(IFS)为编码方法对图像进行压缩处理.IFS的分形编码是将原始图像分割成互不重叠的小方块然后对每个小方块构造迭代函数系统,并保证迭代函数迭代变换的收敛性.由于记录分形变换仅需很少的数据量,这就意味着分形图像编码可以获得很好的压缩效果而且解码速度快.This paper deals with image compression with the aid of Iterated Function System (IFS) .The IFS divides an original image into small non-overlapped blocks and then constructs IFS for each block, meanwhile ensuring the convergence of the iterated transformation. Because only a small fraction of data are needed to record fractal transformation, fractal image encoding can acquire better compression effect as well as quicker decoding speed.
