【Abstract】 A method of the fractal image compression based on region partition is designed, which is used to merge the neighboring sub-regional pairs according to the principle of the least collage errors. Compared to the present widely used fractal image compression method based on block partition, a higher compression ratio can be achieved compared to the same sign to noise ratio.更多还原
