DESCRIPTION:Prof. Nir Sochen\, Uni. of Tel-Aviv\nWe present in this talk a
  unifying generalization of the Mumford-Shah functional\, in the Ambrosio-
 Totorelli set up\, and the Beltrami framework. The generalization of the A
 mbrosio-Tortorelli is in using a diffusion tensor as an indicator of the e
 dge set instead of a function. The generalization of the Beltrami framewor
 k is in adding a penalty term on the metric such that it is defined dynami
 cally from minimization of the functional. We show that we are able\, in t
 his way\, to have the benefits of true anisotropic diffusion together with
  a dynamically tuned metric/diffusion tensor. The functional is naturally 
 defined in terms of the vielbein-the metric's square root. Preliminary res
 ults show improvement on both the Beltrami flow and the Mumford-Shah flow.
