Patent ID: 7864365

Claim:
A method for segmenting a digital image into regions, said method comprising: a. in a computing system comprising at least one computing device, determining a frequency-of-occurrence of a plurality of pixel values in a digital image comprising pixels, wherein said determining comprises excluding at least one of said pixels in said digital image from said determining; b. identifying at least one pixel value associated with a peak frequency-of-occurrence; c. associating said at least one pixel value with an image label, thereby producing an association between said at least one pixel value and said image label; d. determining a candidate pixel location in said digital image; e. labeling said candidate pixel location based on said association; f. determining an unreliable-pixel location in said digital image, wherein said unreliable-pixel location is not said candidate pixel location; g. determining a class label for said unreliable-pixel location based on said association between said at least one pixel value and said image label; h. accumulating a frequency-of-occurrence of said image label among a plurality of neighboring pixel labels; and i. labeling said unreliable-pixel location based on a comparison between a threshold value and said frequency-of-occurrence of said image label among said plurality of neighboring pixel labels.
