| 摘 要： | 鉴于传统的去噪方法难于在时频域得到很好的兼顾,提出一种基于小波变换的去噪方法.通过对图像实施二维离散小波变换,在小波域中,选取适当的阈值对小波系数进行处理.Matlab仿真试验表明,具有很好的效果.

| Abstract: | Considered the traditional denoising method is hard to get good effect both in the time domain and frequency domain,this paper gives a denoising method based on the wavelet transform.This method by imposing the two dimensions discrete wavelet transform on the image,in the wavelet domain,by selecting appropriate threshold value,we can deal with the wavelet coefficient.the Matlab simulation experiment shows the effect is very good. |
