WebSorted by: 8. Jittering and dithering are both techniques of adding noise to reduce visible artefacts (such as banding) in an image. They solve different kinds of artefacts so they are used in different situations. Jittering moves sample positions in space to reduce artefacts caused by regular sampling. Dithering changes the way colours are ...
