This work represents a survey of the main image denoising and inpainting techniques based on variational (enery-based) schemes that lead to nonlinear partial differential equation (PDE) –based filtering models. The variational denoising and restoration approaches are described first. Then, the energy-based structural image reconstruction models are surveyed here. Some of our own variational techniques proposed in these closely related image processing and analysis domains, will be also briefly described in this article.
