Abstract:
1. A method for converting an image comprising a total number of colors greater than a predetermined maximum color count to a color-reduced image, the method comprising the steps of: receiving, by one or more processors, an image comprising a plurality of pixels, wherein each pixel is characterized by an associated color value; generating, by one or more processors, a color-reduced image by setting the associated color value of each pixel in the image to a nearest color in a predetermined reduced set of colors; iteratively, until the total number of colors in the color-reduced image is not greater than the predetermined maximum color count, by one or more processors: wherein the selected identified color pair is selected based on color similarity and on edge characteristics of boundaries between regions in the color-reduced image comprising pixels characterized by the first color of the selected identified color pair and regions in the color-reduced image comprising pixels characterized by the second color of the selected identified color pair.
