摘要：

In this paper we demonstrate the use of an anisotropic PDE to improve the behavior of first and second derivatives of a distance function. We begin by deriving a property of these derivatives and showing a natural relationship between this property and the anti-geometric heat flow. We then construct a PDE that combines a known first-order PDE with the anti-geometric flow and then demonstrate its effectiveness with a discrete simulation.
