Image Progressive Transmission and Lossless Coding Using Fractal Image Coding

ＤＣＴ域分形图像压缩编码方法，其压缩后恢复的图像具有很好的图像质量，文中提出一种新的基于ＤＣＴ域分形图像有损压缩的图像级进式传输和无损压缩方案。实验结果证明了该方案的可行性。

Fractal image coding in DCT domain is studied in this paper.Then a progressive image transmission sheme is presented.Because of the advantage of the fractal image coding in DCT domain,the progressive image transmission sheme is produced.The sheme has an iterative structure,and at each stage a fraction of the image information is transmitted.From the progressive transmission thought,a lossless image coding method is developed.Finally,the results show that the progressive image transmission sheme and the lossless image coding sheme are practical.
