A novel variable-rare vector quantizer (VQ) design algorithm using both gen
eric and fuzzy clustering techniques is presented. The algorithm, termed ge
netic fuzzy entropy-constrained VQ (GFECVQ) design algorithm, has a superio
r rate-distortion performance than that of the existing variable-rate VQ de
sign algorithms. The algorithm utilizes fuzzy clustering technique to enhan
ce the rate-distortion performance for the VQ design. In addition, a novel
genetic algorithm is employed to ensure the robustness of the performance a
gainst the selection of initial parameters. Simulation results demonstrate
that the FECVQ can be an effective alternative for the design of variable-r
ate VQs.
