A two-stage method for reconstruction of parameters in diffusion equations
Xuesong Bai, Elena Cherkaev, Dong Wang
Parameter reconstruction for diffusion equations has a wide range of applications. In this paper, we proposed a two-stage scheme to efficiently solve conductivity reconstruction pr…
An efficient unconditionally stable method for Dirichlet partitions in arbitrary domains
Dong Wang
A Dirichlet -partition of a domain is a collection of pairwise disjoint open subsets such that the sum of their first Laplace--Dirichlet eigenvalues is minimal. In this pape…
An efficient iterative method for reconstructing surface from point clouds
Dong Wang
Surface reconstruction from point clouds is a fundamental step in many applications in computer vision. In this paper, we develop an efficient iterative method on a variational mod…
Diffusion generated methods for denoising target-valued images
Braxton Osting, Dong Wang
We consider the inverse problem of denoising an image where each point (pixel) is an element of a target set, which we refer to as a target-valued image. The target sets considered…
An efficient threshold dynamics method for wetting on rough surfaces
Xianmin Xu, Dong Wang, Xiaoping Wang
The threshold dynamics method developed by Merriman, Bence and Osher (MBO) is an efficient method for simulating the motion by mean curvature flow when the interface is away from t…
