| Abstract: | A genetic algorithm is proposed for obtainment of the matching domain blocks of fractal partition in image compression. It makes use of the partition iterated function system and fractal image compression. Adopted are the domain blocks coding scheme using classification, the crossing position probability and the adaptive fitness function. The algorithm is robust and optimal. Both theoretical analyses and experiments show that higher compression ratio and image quality can be achieved. Parallel computation of genetic algorithms could reduce time cost in fractal compression. |
