The Optimal Quantization Web Site · Home · Downloads · Publications · Symposium · Contact · Home » Vector quantization and signal compression  Vector quantization (VQ) is a classical quantization technique from signal processing that allows the modeling of probability density functions by the distribution of prototype vectors. Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. This book is devoted to the theory and practice of signal compression; i.e. data compression applied to signals such as speech, audio, images and video signals. In the vector quantization (electrical engineering) literature J is known as the.
