Improved fractal image coding based on quadtree partition
Chen Ji-rong · Jisuanji gongcheng · 2005
In fractal image compression, it takes quite long time to look for the best matching block.A method of fractal image coding was put forward based on quadtree image partition and class fuction as well as Y function. The method divides image blocks into 24 species, and then determines one transformation efficiently without carrying out various transformations on every definition domain block. Experiments prove that this method accelerates the speed of coding and the image quality of decoding dosen't decline obviously.
