Abstract :
Minimizing the distortion subject to a cost constraint is fundamental in the design of tree-structured vector quantizers. Because of various competing cost measures, the use of single-cost constraints has led to undesirable results. The author studies the relationships among several cost functions and shows how multiple-cost constraints can be used to significantly improve tree design
