摘要
提出一种对于受高斯白噪声污染的图像压缩编码方法。首先对图像进行离散小波变换 ,然后对其小波变换域系数采用软阈值收缩方法实现去噪 ,最后利用零树方法对其进行压缩编码。实验结果表明 ,所提出的方法不仅能获取较高的图像压缩率 ,而且能较好地去除噪声。
This paper presents a compression and coding method for image with Gaussian white\|noise polluted.Firstly, the image is discrete wavelet transformed,then the noise is removed by soft\|threshold method,and at last we compress and code it by using zerotree method.The experimental result shows that our method can not only achieve high compress ration,but also remove noise well.
