Patent ID: 7715622

Claim:
A method for analyzing an image, said image being formed of a plurality of pixels, wherein each pixel of said plurality of pixels includes a plurality of color channels, each color channel of said plurality of color channels having a channel level within a range of channel levels corresponding to said each pixel, comprising: designating from said plurality of color channels a primary channel, a secondary channel, and a tertiary channel; generating histogram data form said image using said plurality of pixels to form a histogram having a first axis and a second axis based on said primary channel, said first axis pertaining to said range of channel levels within said primary channel, and said second axis pertaining to a number of pixels of said image at each said level within said primary channel; and reorganizing said histogram based on said secondary channel and said tertiary channel to form a multi-dimensional histogram, wherein said reorganizing said histogram is based on determining a channel level difference as between said secondary channel and said tertiary channel for said each pixel, wherein at least one of the designating, the generating and the reorganizing is performed by a computer executable process stored on a computer readable storage medium.
