The conventional color histogram retrieval method is prone to lo se the spatial information of colors. This paper proposes a novel color histogram approach for image retrieval. The histogram is built over groups of circular rings over the image. It keeps the advantages of the robust to the image rotation and scaling of the traditional histogram and incorporates the spatial information of pixels. An additional advantage is the consideration of perceptual sensitivity to the colors located in the central image by the use of a weighting factor of the histogram. The experimental results show that the recall and precision of this proposed approach is better than the others’ histogram methods.
