Scalar and Vector Quantization
Timo Kaukoranta · 2003
Abstract Scalar quantization is a basic technique for analog‐to‐digital signal transformation. It has an extensive theoretical background in addition to the practical usefulness. Vector quantization offers very good possibilities for lossy signal compression. The method has the great advance that its decoding runs extremely fast. Unfortunately, it includes other complexity problems such as the construction of the codebook, the search of the nearest reproduction vector, and the storage of the codebook. This work describes the basic properties of quantization and introduces several vector quantization structures briefly. Most common methods for codebook construction are described also.
