Abstract:

This paper gives an image retrieval method based on the color-space histogram.First,it uses the HSI color space to  compres the color space to 72 kinds of representative colors,and then designs 12 overlapped sub-regions to get the color accumulative histogram in each region. Finally, the similarity iscalculated based on the accumulate.re histogram of each region. The proposed method is simple, flexible and effective in describing the color feature,  which avoids the shortcoming of losing the space distribution in formation in the color histogram. The experimental resuhs show the superiority of the p roposed algorithm in image retrieval precision.
