Abstract: A new image retrieval method based on region is proposed in this paper.First，a method of color clustering is employed to divide images into regions and low-level feature for the color，position，shape of each region are subsequently extracted.Then this paper implements similarity measurement of two images by taking into consideration the similarity of every region synthetically.In order to improve the precision of image retrieval，a relevance feedback mechanism，based on support vector machines is invoked.The experiment results show that the color image retrieval based on object regions is superior to that based on global image features.
