'''Quantization''', involved in [[image processing]]. Quantization techniquesis generallya compresscompression technique achieved by compressing a range of values to a single quantum value. By reducing the number of discrete symbols in a given stream, the stream becomes more compressible. For example seeking to reduce the number of colors required to represent an [[image]]. Another widely used example — [[DCT]] data quantization in [[JPEG]] and [[DWT]] data quantization in [[JPEG 2000]].
