DESCRIPTION:The world is a dynamic 3D environment and if we want computers
  to reason usefully about the world\, they should do so in 3D. To this end
 \, this talk will give an overview of how physics-based priors can be used
  in computer vision to improve 3d reconstructions from ambiguous videos. I
 t will touch on previous work in part-based modelling [1]\; constraints ar
 ising in self-supporting structures [2]\; the use of Hook's law in modelli
 ng the surface of deformable objects [3]\; and the combination of these te
 chniques with  shape from shading [4].\n\n \n\n[1] Video pop-up: Monocular
