In this paper, we propose a image retrieval algorithm using spatial information and color changing ratio. The proposed method extracts color regions from images by threshold to extract spatial information. During this process, we count extracted color regions and color changing, and these values are used to obtain color changing ratio. Image similarity between images is measured by extracted spatial information. Additively, color changing ratio makes images that has similar color changing ratio to be more higher retrieval rank. In our experiment using various natural images, we demonstrate a proposed method shows better performance than other common retrieval methods using color informations.
