Non-linearly weighted fuzzy correlation for color-image retrieval
Guoguang Mu, Hongchen Zhai, Siyuan Zhang · Chinese Optics Letters · 2003
An algorithm with non-linear weight factors in the summation process for fuzzy correlation of color histograms is presented, in which non-linear weights are assigned to some characteristic colors of interest. Experimental results show that this can improve the retrieval of color images with partial aberrations or with local color characters.
