Patent ID: 7133555

Claim:
A method of matching color images comprising: determining pixel intensity count for color components of color images in a database and for a query color image; computing a fuzzy similarity and/or a fuzzy dissimilarity between the query image and the database images based at least in part on the pixel intensities counts; selecting an image from the database based at least in part on the computed fuzzy similarity and/or dissimilarity, wherein computing a fuzzy similarity and/or dissimilarity includes computing the matching intensity, given by the following relationship: ∑ i = 1 p ⁢ ⁢ min ⁡ ( μ i ⁡ ( a ) , μ i ⁡ ( b ) ) ∑ i = 0 p ⁢ ( ⁢ min ⁡ ( μ i ⁡ ( a ) , μ i ⁡ ( b ) ) + α · min ⁢ ( μ i ⁡ ( a ) , 1 - μ i ⁡ ( b ) ) + β · min ⁡ ( 1 - μ i ⁡ ( a ) , μ i ⁡ ( b ) ) ) .
