Augmented Lagrangian Method for A Mean Curvature Based Image Denoising Model Wei Zhu ∗, Xue-Cheng Tai †, and Tony Chan ‡ Abstract High order derivative information has been widely used in developing variational models in image processing to accomplish more advanced tasks. However, it is a nontrivial issue to construct efficient numerical algorithms to deal with the minimization of these variational models due to the associated high order Euler-Lagrange equations. In this paper, we propose an efficient numerical method for a mean curvature based image denoising model using the augmented Lagrangian method.
