New Method of Fractal Image Compression Combined with Adaptive Genetic Algorithms
自适应遗传算法与分形图像压缩结合的新方法*

Put forward the adaptive genetic algorithm proposed for obtainment of matching domain blocks of fractal partition based on fractal and the partition iterated function system,which coded the position of father block with gray code,defined fitness for minimum distance of the child block matching with father block,adjusted GA's controls parameters of across and variance probability adaptively,selected optimal protect policy.After analyzing the experiment results,we can draw a conclusion that this method can shorten compression time greatly and improve the efficiency of research,at the same time,the compression ratio and quality of image after decompression are quaranteed with the same images.
