【Abstract】 In this paper,a new idea of dynamically adjusting infection probability based on the life strength of the virus was presented.A new simulated annealing algorithm with the model of virus evolution was proposed by introducing the improved model of virus evolution in VEGA(virus co-evolution genetic algorithm).The algorithm was applied to solve the problems of codebook design of vector quantization for image coding.The simulation results show that the algorithm has fast convergence rate and good performance for codebook design.更多还原
