Recognition of Similarities and Abnormalities in Chest Radiographs In a medical sense, radiography is an imaging technique to produce a plain image of the human body. Radiography of the chest is the most commonly used medical image acquisition method. In contrast to other imaging techniques, rad...

Robust Heart Valve Modeling & Advanced Computational Decision Support Valvular heart disease (VHD) is a major public health problem with a prevalence of 2.5% in the US. Tens of thousands of minimally invasive procedures are performed every year and new therapeutical approaches are continuous...

Concepts to Computational Constructs: Advanced Scene Understanding for Heterogeneous Artworks Using Deep Learning Due to the mass digitisation of paintings, manual examination and understandingof individual images is a cumbersome task. Developing automatic methods usingcomputer vision and machin...

Obstacle Fusion and Scene Interpretation for Autonomous Driving with Occupancy Grids Autonomous driving is, besides electrification, currently one of the most competitiveareas in the automotive industry. A substantially challenging part of autonomousvehicles is the reliable perception of the dri...

Acquisition- and Reconstruction-Techniques for Sodium Quantification in the Skeletal Muscle using Sodium Magnetic Resonance Imaging (23Na MRI) Measurement of the tissue sodium concentration (TSC) in human tissue offers important insights into pathological- and biological processes with applicat...

Multimodal Assessment of Parkinson's Disease Patients using Information from Speech, Handwriting, and Gait The automatic analysis of different bio-signals from patients with Parkinson’s disease is a highly relevant topic that has been addressed by the research community within several years. Ide...

Advanced 3-D Reconstruction of Talbot-Lau Data X-ray imaging is a standard technique for examinations and interventions in medicine. Based on X-rays, Phase-Contrast Imaging (PCI) can provide an excellent soft-tissue contrast. The most promising setup for measuring phase-contrast in a medical co...

Log File Processing - Changes, Challenges, and Chance Log files are plain text files written by any modern computer system. Their content is determined by logging statements during software development. Thus, any kind of event can be collected during runtime. As a result, logs contain a wealth o...

Analysis of Pathological Speech Signals The present thesis addresses the automatic analysis of speech disorders resulting from Parkinson's disease and hearing loss.For Parkinson's disease, the progression of speech symptoms is evaluated considering speech recordings captured in the short-term (4...

Using Contextual Information to Process Out-of-Vocabulary Words in Spoken Dialog Systems Speech is a very efficient channel for communication, but it is a challenge to cope with words which are unknown to one of the dialogue partners. Human beings are very good at dealing with words that are not...
