摘要
A color characterization method operates to analyze each respective pixel of at least a subset of the pixels of an image object. The image is obtained in HSI format, or alternatively converted from another format to HSI. For each respective pixel, the method determines a color category or bin for the respective pixel based on values of the respective pixel. The color category is one a plurality of possible color categories or bins in the HSI color space. As the pixels are analyzed and assigned to color categories, the method stores information in tho computer regarding the number or percentage or pixels in each of the color categories. A color matching method uses the color characterization method. The color matching method determines similarity of colors between a template image object and a region of interest (ROI). The color matching method first performs the above color characterization technique on each of a template image object and a ROI (region of interest) and then generates match information based on the color information of the template image object and the color information of the ROI, wherein this match information indicates the similarity of colors between the template image object and the ROI.
