Dither
Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of ""mastering"" audio to a CD.A typical use of dither is converting a greyscale image to black and white, such that the density of black dots in the new image approximates the average grey level in the original.
