小波变换在图像压缩中的应用

Application of Wavelet Transform in Image Compress

本文介绍了数据压缩在图像传输中的重要性,并指出了小波变换是实现图像压缩的一种重要的方法,介绍了小波变换是通过对图像像素分解与重构来实现对图像进行压缩,并分析了压缩比。

This paper tells us the importance of data compress in image process ,and it points out that wavelet transform is an important way to do image compress.And wavelet transform does image compress by means of dissolving and re-synthesizing pixel of image. And at last this paper analyzes an important parameter of compress ratio.
