Utilized bidirectional multi-scale aggregation with attention for encoding normal patterns.
Integrated appearance and motion characteristics for abnormality detection.

Main Results:

The proposed BMAN significantly outperforms existing state-of-the-art methods in abnormal event detection.
Achieved robustness to object scale variations and complex motions.
Demonstrated interpretable detection results based on visual event localization.

Conclusions:

The BMAN offers a superior approach to abnormal event detection in video surveillance.
The network's design enhances understanding of detected events.
Ablation studies and feature visualization confirm the network's effectiveness.
