WebJul 1, 2024 · Riemersma dither is a novel dithering algorithm that can reduce a grey scale or colour image to any colour map (also called a palette) and that restricts the influence of a dithered pixel to a small area around it. It thereby combines the advantages of ordered dither and error diffusion dither.
