| Abstract: | Making full use of the correlation of coeffcients of wavelet image,get high compressibility with little distortion.On the basis of existing results,combined with vector quantization coding based on genetic algorithm,we make further improvement of our algorithm.The experiment shows that the algorithm is better than other algorithms in improving the quality of images at the same compression ratio. |
