The Analysis Of Two Kinds Of Image Denoising Models

In this paper, we study two kinds of image denoising models based on two kinds of image noise.ROF model is classical to remove additive noise,we improve the model and give a new method for the existence and uniqueness of the solution,the convergence of the implicit scheme.To remove multiplitive noise,we use the model of G.Aubert,which is called AA model,we improve this model and study the existence and uniqueness of the solution,the convergence of the implicit scheme with the same method.
