Abstract
A novel PDE-based image restoration approach is proposed in this article. The provided PDE model is based on a linear second-order hyperbolic diffusion equation. The well-posedness of the proposed differential model and some nonlinear PDE schemes derived from it are also discussed. A consistent and fast-converging numerical approximation scheme using finite differences is then constructed for the continuous hyperbolic PDE model. Some image restoration experiments using this approach and several method comparisons are also described.
