"WebJan 4, 2024 · Random noise. Back to Wikipedia’s definition of dithering: “Intentionally applied form of noise used to randomize quantization error”. We got the quantization down, and now it says to add noise. Intentionally. Instead of quantizing each pixel directly, we add noise with a value between -0.5 and 0.5 to each pixel.
