Polyconvexification of the multi-label optical flow problem
In this paper the problem of optical flow and occlusion mask estimation is aborded. To that end, we consider a multi-label representation of the optical flow and we define an ener...

Shear Locking in a Plane Elasticity Problem and the Enhanced Assumed Strain Method
The method of enhanced assumed strains (EAS) is a popular tool for avoiding locking phenomena, e.g., a remedy for shear locking in plane elasticity. We consider bending-dominated p...
