A better tree-structured vector quantizer

Abstract

A new vector quantizer permits logarithmic-time encoding and yet performs better than the locally optimal quantizers generated by the LBG algorithm. The success is credited to an elaborated tree-structured optimization process in the codebook design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
