In this paper, based on the adaptive quadtree fractal image coding, the paper studies the matching of the fractal codes under the polar coordinate expression. On this basis, the concept and algorithm of the peak signal-to-noise ratio of the fractal code between the images are proposed And to quantify the similarity between images.Experiments show that the method of image similarity matching based on adaptive fractal coding is very close to human subjective judgment and is very suitable for constructing and managing a large image database
