abstract = {At crowded event entrances, some pedestrians start pushing
others to gain faster access to the events, resulting in
dangerous situations. Pushing identification in video
recordings of events is crucial for understanding pushing
dynamics, thereby managing entrances safely. This talk
presents a deep-learning framework to help researchers
automatically identify pushing in videos of crowds. The
framework consists of four modules: (1) Optical Flow
Estimator that uses a pre-trained optical flow model to
estimate the dense displacement fields from input video. (2)
Wheel Visualization for generating motion information maps
from the displacement fields. (3) EfficientNet-B0 Classifier
that aims to identify pushing behavior from the maps. (4) A
False Reduction and Annotation module; to reduce the number
of false identifications of the classifier, annotate the
regions of pushing and output the annotated video. We used
five real-world ground truth of pushing behavior videos for
the evaluation. Experimental results show that the framework
achieves $86\%$ accuracy. The framework is open-source and
available at https://github.com/PedestrianDynamics/DL4PuDe.},
