Real-Time Event-Based Tracking and Detection for Maritime Environments
This work addresses a domain-specific problem for maritime surveillance, offering an incremental improvement over existing event-based methods.
The paper tackled vessel detection and tracking in maritime environments using event cameras, achieving improved performance by filtering wave-induced events and analyzing cluster movement to reduce false positives.
Event cameras are ideal for object tracking applications due to their ability to capture fast-moving objects while mitigating latency and data redundancy. Existing event-based clustering and feature tracking approaches for surveillance and object detection work well in the majority of cases, but fall short in a maritime environment. Our application of maritime vessel detection and tracking requires a process that can identify features and output a confidence score representing the likelihood that the feature was produced by a vessel, which may trigger a subsequent alert or activate a classification system. However, the maritime environment presents unique challenges such as the tendency of waves to produce the majority of events, demanding the majority of computational processing and producing false positive detections. By filtering redundant events and analyzing the movement of each event cluster, we can identify and track vessels while ignoring shorter lived and erratic features such as those produced by waves.
