CLRmatchNet: Enhancing Curved Lane Detection with Deep Matching Process

Abstract

Lane detection is crucial for safe autonomous navigation, providing essential data for accurate vehicle guidance. Currently, anchor-based detectors are the leading paradigm for lane detection and are commonly combined with a classical label assignment step during training, labeling model predictions for optimal learning. Accurate label assignment has great impact on the model performance, that is usually relying on a predefined classical cost function evaluating GT-prediction alignment. However, classical label assignment methods face limitations due to their reliance on predefined cost functions derived from low-dimensional models, potentially impacting their optimality.

This study introduces MatchNet, a deep learning submodule aimed at addressing challenges in the label assignment stage for lane detection. Integrated into the state-of-the-art lane detection network, CLRNet, MatchNet replaces the classic label assignment process and exhibits significant enhancements, particularly in detecting curved lanes. It raises confidence levels in positive lanes and introduces dynamic flexibility in lane matching. The integrated model, CLRmatchNet, surpasses CLRNet, showcasing substantial improvements in scenarios involving curved lanes, with enhancements of +2.8% for ResNet34, +2.3% for ResNet101, and +2.96% for DLA34.

Assessing the Effect of Floating Photovoltaic Panels on Secondary

Effluents’ Quality – Case Study in Yesodot Reservoir, Israel

Advisor: Prof. Hadas Mamane

Israel is a leading country in wastewater treatment, where 96% of the wastewater was treated in 2020, from which more than 80% were used for irrigation. The Israeli standards for irrigation are divided into restricted and non-restricted, based on the effluents’ quality. The Israeli Ministry of Health regulated that in reservoirs with restricted irrigation effluents’ quality, only 20% of the reservoir can be covered with floating photovoltaic panels. In this study, two data loggers were submerged at 1-1.5m depth in Yesodot Reservoir, which has a floating photovoltaic panels array installed. This study’s objective is to establish an experimental setup for determining the impact of floating photovoltaic panels on a secondary effluents’ reservoir, emphasizing the end of the irrigational season. The specific objectives are to (1) determine the temporal differences in dissolved oxygen and temperature between two locations within the Yesodot Reservoir, one beneath the photovoltaic panels’ array, and the other near the reservoir’s outlet; (2) understand whether the panels cause anaerobic or low dissolved oxygen conditions and/or significant local temperature differences, and (3) conduct comparative analysis between the locations during the end of the irrigation season, while the reservoir reaches its minimal volume and surface area, correlating to the poorest effluent quality.

Abstract: 

Detecting unknown objects in noisy data is a key problem in many fields of science, such as electron microscopy imaging. A common model for the unknown objects is the linear subspace model, which assumes that the objects can be expanded in some known basis (such as the Fourier basis). In this talk, I will present an object detection algorithm that under the linear subspace model is asymptotically guaranteed to find all objects while making only a small percentage of false discoveries.

Amitay is currently a PhD student in the Applied Math department at Tel Aviv University under the supervision of Prof. Shkolnisky Yoel. He received his BSc degree in Mathematics from Tel Aviv University in 2016, and his MSc in Applied Mathematics from Tel Aviv University in 2020. His research interests are in Object Detection, Multiple Hypotheses Testing and Signal Processing.
