Convergent Data-driven Regularizations for CT Reconstruction

1 code implementation14 Dec 2022 Samira Kabri, Alexander Auras, Danilo Riccio, Hartmut Bauermeister, Martin Benning, Michael Moeller, Martin Burger

The reconstruction of images from their corresponding noisy Radon transform is a typical example of an ill-posed linear inverse problem as arising in the application of computerized tomography (CT).

Lifting the Convex Conjugate in Lagrangian Relaxations: A Tractable Approach for Continuous Markov Random Fields

no code implementations13 Jul 2021 Hartmut Bauermeister, Emanuel Laude, Thomas Möllenhoff, Michael Moeller, Daniel Cremers

In contrast to existing discretizations which suffer from a grid bias, we show that a piecewise polynomial discretization better preserves the continuous nature of our problem.

Learning Spectral Regularizations for Linear Inverse Problems

no code implementations23 Oct 2020 Hartmut Bauermeister, Martin Burger, Michael Moeller

One of the main challenges in linear inverse problems is that a majority of such problems are ill-posed in the sense that the solution does not depend on the data continuously.

Exploiting the Logits: Joint Sign Language Recognition and Spell-Correction

no code implementations1 Jul 2020 Christina Runkel, Stefan Dorenkamp, Hartmut Bauermeister, Michael Moeller

We demonstrate that purely learning on softmax inputs in combination with scarce training data yields overfitting as the network learns the inputs by heart.

Fast Convex Relaxations using Graph Discretizations

no code implementations23 Apr 2020 Jonas Geiping, Fjedor Gaede, Hartmut Bauermeister, Michael Moeller

We discuss this methodology in detail and show examples in multi-label segmentation by minimal partitions and stereo estimation, where we demonstrate that the proposed graph discretization can reduce runtime as well as memory consumption of convex relaxations of matching problems by up to a factor of 10.
