SHAMANN: Shared Memory Augmented Neural Networks

no code implementations Cosmin I. Bercea, Olivier Pauly, Andreas K. Maier, Florin C. Ghesu

Current state-of-the-art methods for semantic segmentation use deep neural networks to learn the segmentation mask from the input image signal as an image-to-image mapping.

Efficient and high accuracy 3-D OCT angiography motion correction in pathology

no code implementations14 Oct 2020 Stefan B. Ploner, Martin F. Kraus, Eric M. Moult, Lennart Husvogt, Julia Schottenhamml, A. Yasin Alibhai, Nadia K. Waheed, Jay S. Duker, James G. Fujimoto, Andreas K. Maier

We propose a novel method for non-rigid 3-D motion correction of orthogonally raster-scanned optical coherence tomography angiography volumes.

Deep OCT Angiography Image Generation for Motion Artifact Suppression

no code implementations8 Jan 2020 Julian Hossbach, Lennart Husvogt, Martin F. Kraus, James G. Fujimoto, Andreas K. Maier

The aim of this research is to fill these gaps using a deep generative model for OCT to OCTA image translation relying on a single intact OCT scan.

Fast and robust detection of solar modules in electroluminescence images

no code implementations19 Jul 2019 Mathis Hoffmann, Bernd Doll, Florian Talkenberg, Christoph J. Brabec, Andreas K. Maier, Vincent Christlein

We compare our method to the state of the art and show that it is superior in presence of perspective distortion while the performance on images, where the module is roughly coplanar to the detector, is similar to the reference method.

Learning with Known Operators reduces Maximum Training Error Bounds

no code implementations3 Jul 2019 Andreas K. Maier, Christopher Syben, Bernhard Stimpel, Tobias Würfl, Mathis Hoffmann, Frank Schebesch, Weilin Fu, Leonid Mill, Lasse Kling, Silke Christiansen

We assume that our analysis will support further investigation of known operators in other fields of physics, imaging, and signal processing.

Benchmarking Super-Resolution Algorithms on Real Data

no code implementations8 Sep 2017 Thomas Köhler, Michel Bätz, Farzad Naderi, André Kaup, Andreas K. Maier, Christian Riess

Therefore, current studies are either evaluated 1) on simulated data or 2) on real data without a pixel-wise ground truth.

QuaSI: Quantile Sparse Image Prior for Spatio-Temporal Denoising of Retinal OCT Data

no code implementations8 Mar 2017 Franziska Schirrmacher, Thomas Köhler, Lennart Husvogt, James G. Fujimoto, Joachim Hornegger, Andreas K. Maier

Optical coherence tomography (OCT) enables high-resolution and non-invasive 3D imaging of the human retina but is inherently impaired by speckle noise.
