- W2379024871 abstract "Based on variational level set method,a variational formulation is presented in this paper.The energy functional includes three parts.The first one is data term which is expressed as square of difference between Heaviside function of the original level set function and the evolved level set function.The second part is a regularized term in general form which is expressed as total curvature similar to total variation term used in image diffusion.The third part is a penalty term to avoid re-initialization of level set function.The derived evolution equation is a fourth order partial differential equation which includes advection term and diffusion term.The advection part is discretized by using classic upwind difference scheme,and the diffusion part is discretized by using central difference scheme.Finally,some numerical examples are presented to validate the model for surface diffusion,edge preserving and edge enhancement." @default.
