Jun Tang, Zhentao Wang, Guanyu Hao, Ke Wang, Yan Zhang, Nian Wang, Dong Liang

Abstract: Highlights•By taking the graduality of the anomaly events into account to generate pseudo labels.•Using one-dimensional median filter to constrain the anomaly scores of negative bags.•The network focuses on the most abnormal parts of the frame by the attention module.•The self-guided branch can capture the dependencies between video frames.
