A geometric discretization and a simple implementation for variational mesh generation and adaptation
Weizhang Huang, Lennard Kamenski
We present a simple direct discretization for functionals used in the variational mesh generation and adaptation. Meshing functionals are discretized on simplicial meshes and the J…
Image Segmentation with Eigenfunctions of an Anisotropic Diffusion Operator
Jingyue Wang, Weizhang Huang
We propose the eigenvalue problem of an anisotropic diffusion operator for image segmentation. The diffusion matrix is defined based on the input image. The eigenfunctions and the…
A study on anisotropic mesh adaptation for finite element approximation of eigenvalue problems with anisotropic diffusion operators
Jingyue Wang, Weizhang Huang
Anisotropic mesh adaptation is studied for the linear finite element solution of eigenvalue problems with anisotropic diffusion operators. The M-uniform mesh approach is employed w…
Discrete maximum principle for the weak Galerkin method for anisotropic diffusion problems
Weizhang Huang, Yanqiu Wang
A weak Galerkin discretization of the boundary value problem of a general anisotropic diffusion problem is studied for preservation of the maximum principle. It is shown that the d…
