%X Vector quantization approach high compression ratio,but usually have a domino effect.EZW algorithm in high compression ratio cases recovers images of poor quality.This paper proposes a Improved embedded zerotree wavelet coding method based on the vector quantization.The basic principle is the introduction of the concept of value for the difference image,the difference value image after wavelet decomposition can have a large number of 0 of wavelet coefficients.Using EZW coding will be conducive to improving the quality of reconstructed image.
