Vector quantization is a lossy compression technique used in speech and image coding. In vector quantization, a vector is selected from a finite list of possible vectors to represent an input vector of samples. Each input vector can be viewed as a point in an n-dimensional space. The vector quantizer is defined by a partition of this space into a set of non-overlapping regions. The vector is encoded by the nearest reference vector (known as codevector) in the codebook.
