Anomaly Event Detection in Security Surveillance Using Two-Stream Based Model

<div>The visualization results of our method on testing videos on UCF-Crime. The first row shows the visualization results obtained by our best model variant, and the green block in the gray rectangle represent the ground truth time period in which the anomaly event occurred. The second row presents the visualization results of different variants of our model, including results of ResNet50, ResNet50, ResNet150, and the best model variants, respectively.</div>
