Implementation of fractal image encoding/decoding on DSP

Fractal image compression has been interested due to highly possible compression ratio and selectable quality variation. However, one of disadvantages in fractal image compression is that it takes long time for encoding. So far, there are several methods proposed to get the high speed of encoding such as Fisher's, Hurtgen's and Saupe's, etc. In this paper, implementation of fractal image compression using Fisher's and Hurtgen's methods on DSP TMS320C5515 Stick kit is presented. Experimental results show that the Fisher's method is faster than Hurtgen's while the quality of decoded image (PSNR) is equivalently comparable in these methods.
