Abstract: This paper promotes a new method to de-noise at different stages.Basing at the principle of remote sensing devices to capture images,it introduces an idea of noise-modeling,then de-noises images by the characteristics of different noise models,and finally,recovers the edge and details of the images.Experiments prove that,it can not only de-noise multiple noises efficiently,but also keep the edge and detail information well.It also tests well in classical targets such as SNR and MSE.In a word,this method functions well in de-noising.
