摘要
Fractal image compression is a new technique for encoding image compactly. It builds on local self-similarities within images. It has a character of high compression-ratio and can zoom in or out at will without losing any detail. But it has a disadvantage of lengthy compression time unfit for real-process and practical application. This paper provides an elementary introduction to this compression technique. We survey some of the advanced concepts such as hybrid methods and adaptive portioning. Furthermore, we bring about heuristic searching algorithm to decrease encoding time.
