WebJan 4, 2024 · The threshold map for the random dithering above, literally a map full of random thresholds, is also called “white noise”. The name comes from a term in signal processing where every frequency has the same intensity, just like in white light. The threshold map for O.G. dithering is, by definition, white noise. Bayer Dithering WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
