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. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/creating_plots/chfigu10.html

WebMATLAB uses the Floyd-Steinberg algorithm to perform the mapping. The dithermap is a colormap that replaces the figure colormap (which is not used in this case). The default dithermap contains a sampling of colors from the entire spectrum. This produces reasonably good quality with any object coloring.
