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 WebOct 13, 2024 · Floyd-Steinberg Dithering.

WebFeb 14, 2024 · Introduction. An image can be rendered on a computer screen using millions of colors. In a traditional bitmap, every pixel is represented by a RGB value — the red, green, and blue channels. The value of each color can vary between 0-255. This means there are over 16 million (256 * 256 * 256 = 16,777,216) possible colors!
