Popis
Shrnutí:A hybrid nonlinear PDE-based denoising framework is proposed in this paper. The considered image restoration algorithm is based on a well-posed hyperbolic differential model that combines second-order to fourth-order diffusions. A consistent finite difference method-based numerical approximation algorithm is then constructed for solving this hyperbolic diffusion-based model. Our successful image restoration tests that show the effectiveness of the proposed method are also discussed.
