A New Method for Image Blind Restoration Based on Fourth-order PDE
|
Abstract:
Many of the current methods for image denoising and restoration utilize total variation(TV) regularization to preserve its beneficial edge properties.However a particular caveat of TV regularization is the staircasing phenomenon in recovered images.A new blind restoration model based on a fourth-order partial differential equation(PDE) is proposed for image restoration,which improved the Chan and Wong's TV model.The new method is to introduce fourth-order norm into the energy function instead of TV norm,to ...
