1. A method of occlusion processing that identifies background colors in a video image for the purposes of inserting an indicia into the video image, wherein the background is comprised of two or more colors, comprising: (a) sampling pixels in the video image to obtain a color component value for each pixel; (b) generating a histogram for each of said color component values, wherein each said histogram represents a total number of occurrences of each of said color component values for said sampled pixels; (c) selecting a dominant node from each of said histograms, wherein said dominant nodes identify a background color; (d) is carding each of said sampled pixels having color component values that fall within said dominant nodes from said sampled pixels; and (e) repeating steps (b) through (d) to identify an additional background color.
