Learning Anomalies with Normality Prior for Unsupervised Video Anomaly Detection

ECCV 2024poster

"Unsupervised video anomaly detection (UVAD) aims to detect abnormal events in videos without any annotations. It remains challenging because anomalies are rare, diverse, and usually not well-defined. Existing UVAD methods are purely data-driven and perform unsupervised learning by identifying vario…

Stepwise Multi-grained Boundary Detector for Point-supervised Temporal Action Localization

ECCV 2024poster

"Point-supervised temporal action localization pursues high-accuracy action detection under low-cost data annotation. Despite recent advances, a significant challenge remains: sparse labeling of individual frames leads to semantic ambiguity in determining action boundaries due to the lack of continu…
