In this paper we show that a classic optical ow technique by Nagel and Enkelmann (1986) can be regarded as an early anisotropic di usion method with a di usion tensor. We introduc...
Abstract. In this paper we investigate a family of partial dierential equations (PDEs) for image processing which can be regarded as isotropic nonlinear diusion with an additiona...
We consider di usion processes on a class of R trees. The processes are de ned in a manner similar to that of Le Gall's Brownian snake. Each point in the tree has a real value...
