Donker, Pim (author)This thesis proposes a method of detecting autonomic neuropathy in low-income countries using an infrared camera. Access to healthcare is often limited in low-income countries delaying the detection of neuropathy. If neuropathy can be detected in the earliest stage, often the autonomic state, damage to motor and sensory nerves can be prevented....master thesis 2024

van Geerenstein, Mathijs (author)3D object detection models that exploit both LiDAR and camera sensor features are top performers in large-scale autonomous driving benchmarks. A transformer is a popular network architecture used for this task, in which so-called object queries act as candidate objects. Initializing these object queries based on current sensor inputs leads to...master thesis 2023

Hoogenberg, Friso (author)Gravitational waves predicted by Einstein have been measured in a few observatories worldwide. These detectors are complex interferometers with sizes of kilometers. Misalignments and aberrations in their optical set-up can create higher-order modes in the laser beam. These higher-order mode effects should be compensated to improve the...master thesis 2023

Katkam, Rohan (author)The current wireless networks can face congestion issues due to the increasing number of digital devices. One way to overcome this is to establish communica-tion at a different range of frequencies, specifically in visible light. Most studies in Visible Light Communication (VLC) systems use active light sources like LEDs for transmission, but...master thesis 2023

SUN, Hanchu (author)Surveillance cameras have become increasingly prevalent in public areas worldwide, including in Amsterdam. In Amsterdam, the number and intensity of surveillance cameras in public spaces, such as streets, parks, and plazas, have reportedly increased, even in locations where they were already well-established. In addition to the growing number of...master thesis 2023

de Vries Lentsch, Ted (author)This work addresses visual localization for intelligent vehicles. The task of cross-view matching-based localization is to estimate the geo-location of a vehicle-mounted camera by matching the captured street view image with an overhead-view satellite map containing the vehicle's local surroundings. This local satellite view image can be...master thesis 2022
