New framework SESAD improves video anomaly detection with structured reasoning

Researchers have developed a new framework called SESAD for weakly supervised video anomaly detection. This method tackles the challenge of accurately identifying anomalous events by treating anomaly detection as a structured reasoning process over clip-level visual evidence. SESAD reorganizes clip representations to select relevant semantic information while suppressing scene-related interference, thereby improving detection stability. The framework also incorporates a geometric discrimination module for enhanced anomaly decisions. Experiments on UBnormal, ShanghaiTech, and UCF-Crime datasets demonstrated SESAD's effectiveness, achieving high AUC scores while maintaining computational efficiency. AI
