A new model for image de-noising of partial differential equation

An important feature of scale space is controlled by a partial differential equation(PDE), thus we derive a new method for image de-noising by applying properties of scale space. We give the concrete derivation of the new model and make corresponding experiments. The experimental results indicate that the new method can recover the image well comparing with other classic de-noising methods. Additionally, the new method is also effective in salt and pepper noise. So the new method not only has good effect on image de-noising, but also has superiority in theory.
