摘要
通过对图像的小波变换系数进行阈值操作，可以有效降低噪声，同时又较好地保持图像细节。在文章中详细讨论了这种小波阈值降噪技术，并给出了在此种降噪方法中阈值选取的几种方法。由实验结果可以知道此种小波阈值方法是一种有效的图像降噪方法。
In this paper,the application of wavelet transform in image de noise is studied.Via thresholding operation in wavelet domain of image,it can reduce noise effectively,and at the same time,with a little loss of image detail.Detail discussion of this wavelet thresholding method is presented in this paper,and some methods of threshold selection are also given.It has been proved that the wavelet thresholding technology is an effective method for image de noise.
