Domain Adaptation for Camera-Based River Waste Detection in Durban, South Africa
Master thesis
(2025)
-
K.I. Somers, J.F.P. Kooij, Emre Elbir, Hendrik Kolvenbach, Jakub Tkaczuk, Javier Alonso-Mora
Plastic pollution in rivers is a growing environmental issue with widespread impacts. Monitoring the movement of plastic waste across different river systems is challenging due to environmental variability and the limited availability of labeled data. This thesis investigates camera-based methods for detecting floating macroplastics in rivers and explores ways to adapt detection systems to new locations with minimal data. Collecting data from the Limmat River in Zurich and the uMhlangane River in Durban, South Africa, the study assesses the impact of domain shifts on detection performance and proposes a semi-automated annotation pipeline to improve labeling. Furthermore, it tests techniques like few-shot learning and pseudolabeling to address the performance dip. The results show that model performance decreases significantly when applied to new locations but that even with minimal data, camera-based monitoring can provide useful insights for understanding waste movement and informing plastic waste management strategies.

tunus - tiny house project
An interdisciplinary approach to architecture
Student report

Wim Landuyt, Korneel Somers, Onno Van de Sype, Pieter Van Santvliet, S. Zijlstra, J. Hellendoorn
A tiny house is a building for permanent human habitation that is specifically designed to have a limited ground surface. The tiny house design discussed in this report has a strong focus on circularity, sustainable material usage, smart systems, and affordability. To achieve an overall self-regulating and ecological concept, the aim is to combine and optimise the different flows that go through the tiny house - i.e. electricity, waste, and water. These flows are also smartly integrated and made more efficient on a network scale. Several tunus tiny houses are combined in a village because sustainable living environments can be created more effectively when collaborating in communities. Eventually, the goal is to obtain a network with such flexibility that its principles can be implemented on any collection of tiny houses or even terraced houses and flats.
