| Abstract: | Simulated evolution and simulated annealing are two stochastic search algorithms for solving the global optimization problems.They have been widely used in different engineering areas.An evolutionary simulated annealing algorithm has been proposed in this paper which combines simulated evolution with simulated annealing to solve the codebook design problems of vector quantization for image coding.The simulation results show the algorithm has fast convergence rate and excellent performance for codebook. |
