Abstract :
The paper proposes a novel shock filter for image restoration and enhancement tasks. The method is put in terms of a system of partial differential equations that describes both the evolution of the processed image and of its smoothed second order derivative. The method employs selective smoothing terms acting on robust diffusion directions and its efficiency is proven in the experimental part of the paper on both real and synthetic images.
