| Abstract: | This paper introduced the method of remote sensing image noise reduction based on wavelet analysis of soft thresholding. It was found that the method of wavelet-based image filter can keep the edge detail information of image while reducing remote sensing image noise after comparing with some traditional filter treatments by some indicators. |
