A Variational Reconstruction Method for Undersampled Dynamic X-ray Tomography based on Physical Motion Models

Martin Burger, Hendrik Dirks, Lena Frerking +3

In this paper we study the reconstruction of moving object densities from undersampled dynamic X-ray tomography in two dimensions. A particular motivation of this study is to use r…

Multiframe Motion Coupling for Video Super Resolution

Jonas Geiping, Hendrik Dirks, Daniel Cremers +1

The idea of video super resolution is to use different view points of a single scene to enhance the overall resolution and quality. Classical energy minimization approaches first e…

Adaptive Regularization in Convex Composite Optimization for Variational Imaging Problems

Byung-Woo Hong, Ja-Keoung Koo, Hendrik Dirks +1

We propose an adaptive regularization scheme in a variational framework where a convex composite energy functional is optimized. We consider a number of imaging problems including…
