In this paper, an approach to color-based image retrieval based on histogram combined with color block is proposed. A new 4 dimension vector of image, which is constituted by color histogram, the same color block number, the mean distance among the same color blocks and the mean distance inner color block, is defined. Color histogram, which can capture the global distribution of different intensities or color, is simply to calculate and especially it is not sensitive to image transport and rotation. The last three components are used to capture the spatial information of the image. Experimental results are given to show its ability of identifying images and retrieving similar images. Its performance is better than that of the histogram distance method.
