摘要：

Wavelet transform is a new branch of mathematics, which is developing rapidly in recent years. Because it gets rid of some defects of Fourier transform, Wavelet analysis method has been paid more and more attention and widely used in various fields of engineering application, especially in image processing. In this paper, after the wavelet pyramidal decomposition of the image, the different quantization and coding schemes for each subimage are then carried out in accordance with its statistical properties and distributed properties of the coefficients. The computer simulation result shows that this compression system can attain good reconstructed image while assuring satisfying compression ratio.
