Lagrangian Vector Quantization With Combined Entropy and Codebook Size Constraints


In this paper, the Lagrangian formulation of variable-rate vector quantization is extended to quantization with simultaneous constraints on entropy and codebook size, including variable- and fixed-rate quantization as special cases. The formulation leads to a Lloyd quantizer design algorithm and generalizations of Gersho's approximations characterizing… (More)
