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 deformations. In particular, I will describe methods for computing bounded distortion transformations, locally injective maps whose differentials' conformal distortion is bounded. Toward this end, we developed a convex framework for solving optimization problems over matrices that involve functionals and constraints expressed in terms of their extremal singular values. In addition, I will describe methods for computing physically-motivated elastic maps between shapes. We have applied these methods in a number of challe
