Long Peng-fei · Microcomputer applications · 2005
The image quality of fractal image compression lies on size of child block. By the Quadtrees algorithm we can get the child block bigger where the region has good self-comparable. Otherwise we can get child block smaller.. Thus the Quadtrees algorithm can ensure good image quantity of fractal compression, The evolution algorithm is a random search algorithm. It is faster than method of exhaustion when we search the most matching parent block of a child block in fractal image compression. The article uses Quadtrees and Evolution algorithm to improve the speed of Fractal Image Compression. Experiment results show that this method is successful to be put forward.
