摘要：
In this paper, a fast encoding algorithm is developed for fractal image compression. In order to speed up the encoding process, the range blocks and domain blocks are classified, The match process is limited in a group that has same characteristics. The characteristics are distracted from DCT coefficients. It is shown in software simulation that the encoding time is about ten times faster than that of the baseline method with almost the same PSNR.
