Despite the numerous dithering techniques developed in the last twenty years, the one that has emerged as a standard because of its simplicity and quality of output is the so-called error-diffusion algorithm. This algorithm, first proposed by Floyd and 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 that is restricted to a maximum of 256 colors. See more The algorithm achieves dithering using error diffusion, meaning it pushes (adds) the residual quantization error of a pixel onto its neighboring pixels, to be dealt with later. It spreads the debt out according to the distribution … See more • Atkinson dithering, a variant of Floyd-Steinberg dithering designed by Bill Atkinson See more circuit world technology ltd
