A Variational Level Set Method for Surface Denoising Based on PM Model
|
Abstract:
PM(perona-malik)is a classical nonlinear image diffusion model with adaptive properties of image smoothing and edge preserving.It is transformed to geometric surface smoothing,edge preserving variational model using variational level set method based on the analogue of normal vector of surface and general image intensity in this paper.The energy functional includes three parts.The first part is a data term using the square of the difference between the Heaviside function of initial level set function and th...
