Image Retrieval Based on Fuzzy Color Quantization
Lei Guo · Jisuanji yingyong yanjiu · 2005
Color quantization is an important method of image retrieval based on color feature. By introduction of the fuzzy set theory, a fuzzy color quantization method based on the subjective perception of human is proposed to minimize color quantization error and adapt to the fuzziness of human's perception. Based on the method, fuzzy color-spatial feature is extracted for image retrieval. Experimental results show effectiveness of the quantization method and significant high retrieval accuracy of the algorithm.
