BiPOCO: Bi-Directional Trajectory Prediction with Pose Constraints for Pedestrian Anomaly Detection. (arXiv:2207.02281v1 [cs.CV])

We present BiPOCO, a Bi-directional trajectory predictor with POse
COnstraints, for detecting anomalous activities of pedestrians in videos. In
contrast to prior work based on feature reconstruction, our work identifies
pedestrian anomalous events by forecasting their future trajectories and
comparing the predictions with their expectations. We introduce a set of novel
compositional pose-based losses with our predictor and leverage prediction
errors of each body joint for pedestrian anomaly detection. Experimental
results show that our BiPOCO approach can detect pedestrian anomalous …
