dithered
Dithered is a term used in digital signal processing and computer graphics to describe a technique used to simulate greater color depth or grayscale resolution in images with a limited color palette. It involves intentionally introducing a controlled amount of noise or randomness to the image. This noise is not random in the true sense but is patterned or structured to spread out the quantization error that occurs when a continuous range of tones or colors must be represented by a smaller, discrete set of values.
The process of dithering can be understood as a way to fool the human eye into perceiving
Different dithering algorithms exist, each with its own method of distributing the noise. Some common methods
