Abstract

In this paper, we present a novel approach for image selective smoothing by the evolution of two paired nonlinear partial differential equations. The distribution coefficient in de-noising equation controls the speed of distribution, and is determined by the edge-strength function. In the previous works, the edge-strength function depends on isotropic smoothing of the image, which results in failing to preserve corners and junctions, and may also result in failing to resolve small features that are closely grouped together. The proposed approach obtains the edge-strength function by solving a nonlinear distribution equation governed by the norm of the image gradient. This edge-strength function is then introduced into a well-studied anisotropic distribution model to yield a regularized distribution coefficient for image smoothing. An explicit numerical scheme is employed to efficiently solve these two paired equations.Compared with the existing methods, the proposed approach has the advantages of more detailed preservation and implementational simplicity. Experimental results on the synthesis and real images confirm the validity of the proposed approach.
