Total Variation Regularization for Manifold-valued Data and Beyond 

Nonlinear manifolds appear as data spaces in various applications. Important examples are spheres and the Riemannian manifold of positive matrices. Although very prominent for scalar and vector space valued data, algorithmic schemes for the variational regularization of manifold-valued data using non-smooth functionals have been considered only recently. In this talk, we propose algorithms for the variational regularization of manifold-valued data using non-smooth functionals. In particular, we deal with algorithms for TV regularization and with higher order methods including the TGV denoising of manifold-valued data.
