Researchers have developed a new weakly-supervised method for spatiotemporal anomaly detection in videos. This approach trains a network using only video-level labels, indicating whether a video is normal or contains an anomaly, without requiring detailed frame-by-frame annotations. The system extracts features from clips and employs a multiple instance ranking loss to generate anomaly scores for specific spatiotemporal regions. Results were demonstrated on the UCF Crime2Local Dataset. AI
