ABSTRACT: Ahmad et al. in their paper [1] for the
first time proposed to apply sharp function for classification of images. In
continuation of their work, in this paper we investigate the use of sharp
function as an edge detector through well known diffusion models. Further, we
discuss the formulation of weak solution of nonlinear diffusion equation and
prove uniqueness of weak solution of nonlinear problem. The anisotropic
generalization of sharp operator based diffusion has also been implemented and
tested on various types of images.
