%X A texture based image retrieval algorithm RAH based on the histogram of image power spectral in frequen- cy domain is proposed, which mainly includes the next two parts: first, the method of computing radius histogram and angular histogram and the algorithm of texture feature extraction based on the histogram of image power spectral in frequency domain, second, the similarity measurement function based on the texture feature. The experimental re- sults indicate that RAH is preferable to the traditional co-occurrence matrix based algorithm.
