摘要
In this paper, we propose for the first time an application of fuzzy relations in fuzzy set theory to the measure of color identity, where a membership function is used as a measure of the similarity, and a fuzzy-match of two colors is defined by the alpha-cut fuzzy relation. Besides, a fuzzy-search process of color histograms is developed for the first time to save from massive unnecessary calculations. Experimental results in the application to color-image retrieval confirm the advantages of our approach in both accuracy and efficiency of the color-image retrieval, as predicted in our theoretical analysis.
