摘要
以迭代函数系统为基础的分形图象压缩方法是一种新的有效的图象数据编码途径．在分析分形图象压缩方法优缺点的基础上，提出了一种基于仿射变换的标准图压缩法，此法的恢复图象质量与压缩恢复速度均明显优于分形图象压缩法．
Fractal image compression based on iterated function system is a newly developed effective image coding approach. Based on the analysis of the virtue and shortage of the method,we have proposed another image compression method-image compression based on standardimage. The proposed method uses affine transform with faster compression and restore speed and therefore the quality is better than traditional fractal image compression method.
