Matching image content with bounded distortion
Abstract
Modeling deformations is important for various applications in computer vision, graphics and geometry processing. In this talk I will describe our recent progress in modeling bounded distortion transformations, locally injective maps whose differentials' conformal distortion is bounded. Specifically, I will introduce a convex framework for solving optimization problems over matrices that involve functionals and constraints expressed in terms of the extremal singular values of matrices. Using this framework we can design algorithms for solving a number of challenging problems. In particular, I will present algorithms for finding corresponding points between images related by a non-rigid deformation, non-rigid registration of shape models and computing extremal quasi-conformal maps.
