Abstract: In order to improve the accuracy of video anomaly detection, we propose a video anomaly detection method based on secondary prediction of multi-layer memory enhancement generative adversarial networks. Firstly, a spatiotemporal cube is extracted from target detection, and sent into encoder to obtain a prediction frame. Secondly, the apparent feature of the prediction frame and the optical flow feature of corresponding real frames are fused to form fusion features. Finally, a secondary prediction future frame is generated by using multi-layer memory enhancement generative adversarial networks, for learning normal feature patterns of different levels and capturing the semantic information of context. Experimental results on UCSD Ped2 and CUHK Avenue datasets show that the proposed method can effectively improve the performance of video anomaly detection compared with other video anomaly detection methods, and its frame level AUC reaches 99.57% and 91.59%, respectively.
