WebFeb 21, 2024 · The Floyd-Steinberg algorithm is relatively simple. It scans the image one pixel at a time, scanning the top line from left to right, then the next line, etc. until it reaches the bottom. For a bitonal dither, it's easier if we first convert the whole image to grayscale, so that each pixel has a luminosity (perceived brightness) value of 0 to 255.

WebThis tool allows you to dither any JPG. You can set any number of colors in the options and choose a dithering algorithm. It implements nine dithering algorithms – Floyd-Steinberg, Stucki, Atkinson, Jarvis, Burkes, Sierra, Two-row Sierra, Sierra Lite, and False Floyd-Steinberg. The fewer colors are used in creating a dithered JPG, the more of ...

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
