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

Alfrink, Kars (author), Keller, A.I. (author), Doorn, N. (author), Kortuem, G.W. (author)Local governments increasingly use artificial intelligence (AI) for automated decision-making. Contestability, making systems responsive to dispute, is a way to ensure they respect human rights to autonomy and dignity. We investigate the design of public urban AI systems for contestability through the example of camera cars: human-driven...conference paper 2023

Palffy, A. (author), Kooij, J.F.P. (author), Gavrila, D. (author)Early and accurate detection of crossing pedestrians is crucial in automated driving in order to perform timely emergency manoeuvres. However, this is a difficult task in urban scenarios where pedestrians are often occluded (not visible) behind objects, e.g., other parked vehicles. We propose an occlusion aware fusion of stereo camera and...journal article 2023

Gawehn, M.A. (author)The aim of this study is to innovate wave-based depth-inversion towards smarter and faster algorithms to be used with various remote sensing instruments for broad community use. Wave-based depth inversion describes a branch of coastal remote sensing, which uses video recordings of a wave-field to derive depths and thereby create digital maps of...doctoral thesis 2022

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

Dai, Renjie (author)Workflow analysis aims to improve the efficiency and safety in operating rooms by analysing surgical processes and providing feedback or support, where observations can be made and evaluated by algorithms rather than human experts. For our study, we mount five calibrated cameras from different angles in a Catheterization Laboratory (Cath Lab) to...master thesis 2022

Tempelaar, Willem Jan (author)Multi-pedestrian tracking in camera networks has gained enormous interest in the industry because of its applicability in travel-flow analysis, autonomous driving, and surveillance. Essential to tracking in camera networks is camera calibration and, in particular extrinsic camera calibration. Extrinsic camera calibration incorporates the 3D...master thesis 2022

Verheyen, Jan (author)Insects have — over millions of years of evolution — perfected many of the systems that roboticists aim to achieve; they can swiftly and robustly navigate through different environments under various conditions while at the same time being highly energy efficient. To reach this level of performance and efficiency one might want to look at and take...master thesis 2022

Baratam, Srimannarayana (author)Multi-class road user detection using the next- generation, 3+1D (range, azimuth, elevation, and Doppler) radars has been shown feasible, thanks to the increased density of their point clouds and the inclusion of elevation information. However, object detection networks using LiDAR (64-layer) point clouds still dominate the performance metrics....master thesis 2022
