【Abstract】 Content-based image retrieval(CBIR)is one of the main techniques of multimedia databases.In CBIR,in order to surmount the problem of lacking the spatial knowledge of color histogram and the difficulty of control the scale of single fixed partition approach,we present a novel CBIR algorithm based on multiple sub-regions with different similarity weights.Furthermore,by incorporating the relevance feedback into the weights determination algorithm, experimental results indicate that our approach provides perceptually appealing results and high retrieval rate.更多还原
