Visual-Based Spatiotemporal Analysis for Nighttime Vehicle Braking Event Detection

In this paper, we propose a novel visual-based approach that can detect brake lights at night by analyzing the tail lights based on the theedimensional Nakagami imaging which can provide robust information of brake lights. Instead of using the knowledge of the heuristic features, such as symmetry and position of rear facing vehicle, size and so forth, we focus on extracting the invariant features based on modeling the scattering of brake lights and therefore can conduct the detection process in a part-based manner. Experiment from extensive dataset shows that our proposed system can effectively detect vehicle braking under different lighting and traffic conditions, and thus prove its feasibility in real-world environments.
