Riemannian Mean Curvature Flow
2005In this paper we explicitly derive a level set formulation for mean curvature flow in a Riemannian metric space. This extends the traditional geodesic active contour framework which is based on conformal flows. Curve evolution for image segmentation can be posed as a Riemannian evolution process where the induced metric is related to the local ...

In this paper, we introduce the linear scale-space theory for functions on finite graphs. This theory permits us to derive a discrete version of the mean curvature flow. This discrete version yields a deformation procedure for polyhedrons. The adjacent matrix and the degree matrix of a polyhedral graph describe the system equation of this polyhedral ...

International Journal of Mathematics
A Hermitian curvature flow is proposed and some regularity results are obtained. The stationary solution to the flow, if exists, is a balanced metric which is also Hermitian Yang–Mills with respect to itself.

Volume preserving anisotropic mean curvature flow
Indiana University Mathematics Journal, 2001In this nice paper, the author studies anisotropic analogues of the volume-preserving mean curvature flow. He proves that an evolving arbitrary convex hypersurface is smooth and remains convex for times \(t>0\), and converges to the ``Wulff shape'' determined by the anisotropy. This is a natural extension of classical mean curvature results.
