Abstract—A novel fourth-order Partial Differential Equation (PDE) - based image restoration technique is proposed in this work. It is based on a well-posed ...

This paper presents an edge-preserving fourth order partial differential equation (PDE) for image restoration derived from a new surface-based energy ...

We proposed a fourth-order image denoising model. Using the fixed point theorem, we established the existence and uniqueness of the entropy solution.

Nonlinear diffusion-based image restoration models can be divided into second- and fourth-order PDE- based approaches. The second-order PDE models have been ...

Jun 27, 2013 · It combines a second-order filter with a fourth-order filter. The combined method takes the advantage of both filters since it can preserve ...

This program can restore an image with holes cut in it by propagating (or diffusing) the grayscale values surrounding each hole toward the hole's center.
