Abstract: | An image filter based on nonlinear discontinuous partial differential equation (PDE) is presented. It models a class of morphological
image filters called the level set method for gray image processing. We discuss the theoretical aspects of this PDE. The switch
signal is controlled by the discontinuous right hand of PDE. We propose a discrete algorithm for its numerical solution and
corresponding filter implementation. The study provides insights via several experiments. These types of filters are very
useful in numerical image analyses. |
