 In the first half of the talk I will give an overview of a few popular PDE models and variational formulation in image processing. 
  
In the second half of the talk I will present our recent work on a novel phase space method for reconstructing the index of refraction 
  
of a medium from travel time measurements. The method is based on linking two metrics of a Riemannian manifold. In particular 
  
this phase space formulation can deal with multiple arrival times as well as anisotropic media naturally.
