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. %K Maximal Function %K Sharp Function %K Image Processing %K Edge Detection %K Nonlinear Diffusion %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=56749
