SigSegment: A Signal-Based Segmentation Algorithm for Identifying Anomalous Driving Behaviours in Naturalistic Driving Videos
This addresses distracted driving detection for road safety, but appears incremental as it builds on existing CNN-LSTM approaches with signal-based segmentation.
The paper tackles the problem of identifying distracted driving behaviors in naturalistic driving videos by proposing a signal-based segmentation algorithm that uses a deep CNN-LSTM classifier to detect anomalous events. The method achieved an overlap score of 0.5424 and ranked 9th in the AI City Challenge 2023.
In recent years, distracted driving has garnered considerable attention as it continues to pose a significant threat to public safety on the roads. This has increased the need for innovative solutions that can identify and eliminate distracted driving behavior before it results in fatal accidents. In this paper, we propose a Signal-Based anomaly detection algorithm that segments videos into anomalies and non-anomalies using a deep CNN-LSTM classifier to precisely estimate the start and end times of an anomalous driving event. In the phase of anomaly detection and analysis, driver pose background estimation, mask extraction, and signal activity spikes are utilized. A Deep CNN-LSTM classifier was applied to candidate anomalies to detect and classify final anomalies. The proposed method achieved an overlap score of 0.5424 and ranked 9th on the public leader board in the AI City Challenge 2023, according to experimental validation results.
