算术编码在分形图象压缩中的应用

结合近年来对分形块编码的研究成果，实现了其编码和解码过程；并且通过研究存储数据之间的内在联系，提出对不同的数据按不同的原则进行分类，然后分别施行算术编码。分析数据及实验效果说明，改进的编码算法在不影响信噪比的前提下得到了较好的压缩比。

Arithmetic Coding's Application in Fractal Image Compression

Fractal Image Compression is a valid algorithm. On the foundation of recent research about Fractal Block Coding, this paper completes both the encoding and decoding processes. Furthermore, by analyzing the relation between stored data, the authors first catalog different data according to different rules, then respectively apply Arithmetic Coding on them. The analysises and results show a better compression ratio on the basis of a fixed PSNR.
