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.
