The Color Histogram Image Retrieval Method Based on Granular Computing

The retrieval result of traditional color histogram image is not satisfactory,they only consider the statistical information about color and forget its spatial distribution information.In this paper,a color histogram image retrieval method based on granular computing was put porward,which use more size,multi-level and perspectives thought of granular computing and keep the spa tial distribution information of color histogram image,and then granulating the quantizing interval of color histogram image,pro ceeding similarity matching according to histogram intersection distance method.To keep the retrieval efficiency in the premise of precision,the experiment result shows that the algorithm has better precision and recall rate.
