Abstract:
1. A method for processing an image containing a plurality of pixels, the method comprising: selecting one of the plurality of pixels; obtaining color values for said selected pixel, said color values representing values in a first color space; converting said color values for said selected pixel to color values for said selected pixel in a second color space; obtaining color values for a plurality of pixels in a vicinity of said selected pixel, said color values representing values in said first color space; converting said color values for said plurality of pixels in the vicinity of said selected pixel to color values for said plurality of pixels in said second color space; determining a plurality of differences between the color values of the selected pixel and the color values of each pixel of said plurality of pixels in the vicinity of said selected pixel; comparing each of said plurality of differences with one of a plurality of predetermined thresholds; and responsive to a determination that a number of pixels in the vicinity of said selected pixel for which at least one of said plurality of differences was above a predetermined threshold is above a predetermined anomaly threshold, setting a new color value for at least one color channel of said selected pixel to a highlight color value.
