Iterative Reconstruction Methods for Accelerating Quantitative Abdominal MRI Abstract Abdominal pathologies, in particular, diffuse liver disorders are affecting a rapidly increasing group of people worldwide. Non-alcoholic Fatty Liver Disease (NAFLD) parallels a global epidemic and is the m...

Handwriting with Focus on Writer Identification and Writer Retrieval Abstract In the course of the mass digitization of historical as well as contemporary sources, an individual examination by means of historical or forensic experts is no longer feasible. A solution could be an automatic han...

Fully Automatic Segmentation of Anatomy and Scar from LGE-MRI Abstract The leading cause of death worldwide are cardiovascular diseases. In addition, the number of patients suffering from heart failure is rising. The underlying cause of heart failure is often a myocardial infarction. For dia...

Automated Glaucoma Detection with Optical Coherence Tomography Abstract The number of patients suffering from the glaucoma disease will increase in the future. A further automation of parts of the diagnostic routine is inevitable to use limited examination times more efficiently. Optical coh...

3-D/2-D Registration of Left Atria Surface Models to Flouroscopic Images for Cardiac Ablation Procedures Abstract Atrial fibrillation is one of the most common cardiac arrhythmias. It can be treated minimally invasive by catheter ablation. For guidance during the intervention, augmented fluo...

Dynamic Cardiac Chamber Imaging in C-arm Computed Tomography Cardiovascular diseases, i.e. disorders pertaining to the heart and blood vessels, are a major cause of mortality in developed countries. Many of these disorders, such as stenoses and some cases of valvular dysfunction, can be diagnos...

Accurate Measurements with Off-the-Shelf Range Cameras Abstract Distance cameras have gained large popularity in the last years. With more than 24 million Microsoft Kinect units sold and the proliferation of 3-D sensors for biometric authentication, these cameras have reached the mass market...

Multi-Frame Super-Resolution Reconstruction with Applications to Medical Imaging Abstract The optical resolution of a digital camera is one of its most crucial parameters with broad relevance for consumer electronics, surveillance systems, remote sensing, or medical imaging. However, resolut...

Signal Processing for Interventional X-ray-based Coronary Angiography Abstract Rotational angiography using C-arm scanners enables intra-operative 3-D imaging that has proved beneficial for diagnostic assessment and interventional guidance. Despite previous efforts, rotational angiography wa...

Interactive Analysis of Multispectral and Hyperspectral Image Data Abstract A multispectral or hyperspectral sensor captures images of high spectral resolution by dividing the light spectrum into many narrow bands. With the advent of affordable and flexible sensors, the modality is constantl...
