An Image Segmentation Algorithm Based on Level Set Using Discontinue PDE

It present a nonlinear discontinue partial differential equation (PDE) that models a class of morphological image filters, the level set method for gray image processing. We discuss theoretical aspects of this PDE. The switch signal is controlled by the discontinue right hand of PDE. We propose a discrete algorithm for its numerical solution and corresponding filter implementation. It provides insights via several experiments. These types of filters are very useful in numerous image analyses.
