A New Baseline for Feature Description on Multimodal Imaging of Paintings

Multimodal imaging is used by conservators and scientists to study the composition of paintings. To aid the combined analysis of these digitisations, such images must first be aligned. Rather than proposing a new domain-specific descriptor, we explore and evaluate how existing feature descriptors from related fields can improve the performance...

Point-based morphological opening with input data retrieval

Mathematical morphology is a technique recently applied directly for point cloud data. Its working principle is based on the removal and addition of points from an auxiliary point cloud that acts as a structuring element. However, in certain applications within a more complex process, these changes to the original data represent an...

Quantification of Imaging Biomarkers For Cardiovascular Disease in CT(A)

For better management of cardiovascular disease, it is of utmost importance to categorize the subjects into different risk groups. This categorization can be made based on cardiovascular risk factors including the family history of the subject. Imaging techniques play an increasing role in order to assess ardiovascular risk factors. In this...

Statistical Modeling of Shape and Motion of the Wrist Bones

Carpal instability occurs when the wrist bones assume a pathological posture, e.g. due to ligament rupture as a result of trauma. Ligament rupture cannot be diagnosed reliably directly, as current medical imaging modalities do not provide sufficient soft-tissue contrast (X-ray, CT) or lack a sufficiently high resolution (CT, MRI). Ligament...

Pose estimation for mobile devices and augmented reality

In this thesis we introduce the reader to the field of Augmented Reality (AR) and describe aspects of an AR system. We show the current uses in treatment of phobias, games, sports and industry. We present the challenges for Optical See-Through Augmented Reality in which the real world is perceived normally by the user and is augmented with...
