ABSTRACT
This work addresses the problem of robust vector quantization in the scenario of image transmission over a binary symmetric channel. The application of the algorithm Variable Neighborhood Search (VNS) is introduced for the purpose of index assignment of codevectors. Simulation results reveal that the algorithm VNS, when compared to Simulated Annealing and Genetic algorithm, produces codebooks with the same robustness to channel erros with the spent of minor time.
