Generative Cooperative Learning for Unsupervised Video Anomaly Detection [PDF]
Computer Vision and Pattern Recognition, 2022 Video anomaly detection is well investigated in weakly-supervised and one-class classification (OCC) settings. However, unsupervised video anomaly detection methods are quite sparse, likely because anomalies are less frequent in occurrence and usually ...
