'''Quantization''', involved in [[image processing]], is a [[lossy compression]] technique achieved by compressing a range of values to a single quantum value. By reducingWhen the number of discrete symbols in a given stream is reduced, the stream becomes more compressible. For example, seeking to reducereducing the number of colors required to represent ana digital [[image]]. Anothermakes widelyit usedpossible exampleto reduce its file size. Specific applications include [[Discrete cosine transform|DCT]] data quantization in [[JPEG]] and [[Discrete wavelet transform|DWT]] data quantization in [[JPEG 2000]].
