Denoising of image gradients and total generalized variation denoising
Birgit Komander, Dirk A. Lorenz, Lena Vestweber
We revisit total variation denoising and study an augmented model where we assume that an estimate of the image gradient is available. We show that this increases the image reconst…

A Sinkhorn-Newton method for entropic optimal transport
Christoph Brauer, Christian Clason, Dirk Lorenz +1
We consider the entropic regularization of discretized optimal transport and propose to solve its optimality conditions via a logarithmic Newton iteration. We show a quadratic conv…
