Floyd-Steinberg Dithering / The Coding Train

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 Web左：原图；中：Floyd–Steinberg dithering；右：Ordered dithering。图源 wiki. 我们今天讨论的就是 ordered dithering。之所以只讨论这个，理由是：简单; 像素游戏中常见的就是这种抖动（主要还是因为简单），这种抖动也最容易营造像素的氛围 port moresby war cemetery records
