Linear co-volume scheme for anisotropic curvature driven motions
We introduce a linear semi-implicit complementary volume numerical scheme for solving level-set-like nonlinear diffusion equations arising in plane curve evolution driven by curvature and anisotropy. The scheme is L ∞ and W 1,1 stable and the efficiency is given by its linearity. Incomplete Cholesky preconditioners are used for computing rapidly the linear systems which arise. Computational results related to anisotropic mean curvature motion in a plane are presented.
