This paper presents a new image retrieval method based on shape, first the image is divided into central and lateral annular two region, adjacent corner interval degree is calculated in the region, the interval is quantified some grades, and thus calculate each image in each region of the adjacent corner interval histogram, the two images of the similarity depends on the corresponding region histogram Euclidean distance. The algorithm has the translation, rotation and scale invariant features, the experiment proves that it has better image retrieval efficiency.
