Rotated Barnes-Wall lattice based vector quantizer and its application in image-sequence coding

  • Published:
Journal of Electronics (China)

Abstract

A new scheme is presented to design a rotated Barnes-Wall lattice based vector quantizer(LVQ). The construction method of the LVQ and its, fast quantizing algorithm are described at first. Then gain-shape lattice vector quantizer (GSLVQ) with LVQ as shape quantizer is discussed. Finally the GSLVQ is used in image-sequence coding and good experimental results are obtained.
