Digital image compression using a genetic algorithm

A digital image compression method based on a VQ coding technique is presen ted in this paper. Genetic algorithm is used to generate a good global opti mal codebook. In the genetic algorithm, it is proposed that movable genes b e used to improve the computing effect of the algorithm. Both the encoding and decoding have been simulated on a computer and the reconstructed images and experiment results show that the algorithm is reliable. The method may be applied to compression coding for all still images and image sequences. Also the genetic algorithm may be used in other optimal fields.
