A 1-bit image of the Statue of David, dithered with Floyd–Steinberg algorithm Floyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg. It is commonly used by image manipulation software, for example when an image is converted into GIF format, which is restricted to a maximum of 256 colors. The algorithm achieves dithering using error
