【Abstract】 A method that estimates image′s self-similarity is presented and the factor denoting the character of image′s self-similarity is defined. Comparing the factors of different images, the difference of self-similarity can be found.And then it can be found whether a given image fits the method of fractal image coding based on the parameter. Experimental results show that the algorithm can evaluate image′s self-similarity character well.更多还原
