Patent ID: 8270709

Claim:
A computer-implemented method for processing an image on a computer system comprising: receiving an indication of a first region within an image; processing a predetermined portion of pixels within the first region to generate a plurality of color values according to a first predetermined color space; processing the plurality of color values to determine a dominant base color; computing, by operation of a processors, perceptual color differences between the dominant base color and second colors in the image, the second colors being associated with pixels within a predetermined portion of the image; comparing the perceptual color differences against a perceptual color tolerance; classifying, by operation of the processor, the pixels in dependence upon at least the result of the comparison, wherein the classification of each pixel indicates a relative degree to which the color values of that pixel are modified by editing modifications; presenting to a user the result of classifying the pixels within the predetermined portion of the image; and modifying the pixels within the predetermined region of the image in dependence upon at least a previously selected process and the classification of the pixels.
