Research of Image Retrieval Based on Color

Research on image retrieval technology based on color feature, for the color histogram with a rotation, translation invariance of the advantages and disadvantages of lack of space, a color histogram and color moment combination image retrieval. The theory is a separate color images and color histogram moment of extraction, and then two methods of extracting color feature vector weighted to achieve similar distance, similar to the last distance based on the size of the return search results, based on the realization of the characteristics of the color image retrieval system. The results show that the method is rotation, translation invariance, a single method of extracting color features, enhanced image search and improve the accuracy of the sort.
