Abstract

A system and method for finding areas of similar color in electronically captured spot color images and replacing the similar colors with a single dominant color. An original image is first prescanned at low resolution to generate an electronic image. Using information from the prescan step, the system classifies colors in the generated image using a three dimensional histogram. A pallet of dominant colors is identified based on the histogram classification. Each line of the original image is then scanned at a second resolution, the second resolution being substantially higher than the first resolution. The scanned lines are then processed to determine where within each line different colors exist. The locations of the different colors are noted using a break out box comprising a set of rules to evaluate each pixel. Segments of each line are correlated with each other and with segments of adjacent lines to determine if the noted colors are in similar locations to thereby identify various spatial areas of color representing the original. The spatial areas are finally compared with the pallet of colors and the average noted color of the spatial areas are replaced with the closest corresponding pallet color.
