Abstract

A low-complexity, high-performance vector quantization technique for medium to high bit-rate encoding based on multistage (residual) VQ is introduced. The design, a variable rate version of multistage VQ, is the vector extension of the piecewise uniform scalar quantizers of Swaszek and Thomas, and is related to the piecewise uniform VQ’s of Kuhlmann and Bucklew. Examples for the independent Gaussian and Laplacian sources are included. © 1992 IEEE
