VQ-Based Image Coding and Vector Filter Bank

Weiping Li, John Wus, Ya-Qin Zhang

Abstract: It is well known that vector quantisation (VQ) is a good technique for image coding. For VQ-based image coding, vector-based signal processing techniques should be used to better match with VQ. The paper reports some preliminary results of extending the concept of the filter bank from a scalar-based operation to a vector-based operation and the performance of a vector filter bank for image coding.<
