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。 An image compression coding method is proposed for Gaussian white noise pollution. Firstly, the image is decomposed by discrete wavelet transform, and then the wavelet transform coefficients are denoised by soft thresholding method. Finally, the image is compressed by zerotree method. The experimental results show that the proposed method can not only obtain higher image compression rate, but also remove the noise better.
