Variational Model to Removal Strong Multiplicative Noise
In this paper,a new variational model is proposed and studied to remove the strong multiplicative noise.The initial boundary value problem of the partial differential equation for the model is derived and discreted numerically.The model has succeeded in inhibiting multiplicative noise effectively,preserving the textures and fine details of images perfectly.It is concluded from the experiments that the new model not only can remove multiplicative noise effectively,but also is more superior to preventing the "step-casing effect" than the existing key models.Moreover,the new variational model is much superior than the existing key models in the running time.
