Title: Codebook Design Algorithm for Vector Quantization Based on Particle Swarm Optimization
Abstract: A codebook design algorithm for vector quantization based on particle swarm optimization(PSO)is proposed. To solve the shortcoming that the initial codebook selection affects the convergence speed of codebook training and the per- formance of the final codebook,the initial codebook with global characteristics is produced using PSO,and iteratively pro- duce final codebook with local characteristics using Linde-Buzo-Gray(LBG).Both of the theory and practical effect show the rationality of the proposed algorithm.
