It is slower than Floyd–Steinberg dithering because it distributes errors among 12 nearby pixels instead of 4 nearby pixels for Floyd–Steinberg. Stucki dithering is based on the above, but is slightly faster. Its output tends to be clean and sharp. Burkes dithering is a simplified ...

WebWhat is dithering in image processing? In computer graphics, dithering is an image processing operation used to create the illusion of color depth in images with a limited color palette. … The human eye perceives the diffusion as a mixture of the colors within it. Dithering is analogous to the halftone technique used in printing [1]. WebJun 10, 2024 · Positional dithering was more interesting for my use-case, but I find that positional dithering is much easier to reason about and implement anyway. Most of this information probably applies to other dithering methods too. One important thing I figured out the hard way is to always take luminance/luma into account when comparing colors.
