Local Anomaly Detection in Videos using Object-Centric Adversarial Learning
Pankaj Raj Roy, Guillaume-Alexandre Bilodeau, Lama Seoud
We propose a novel unsupervised approach based on a two-stage object-centric adversarial framework that only needs object regions for detecting frame-level local anomalies in video…

Road User Abnormal Trajectory Detection using a Deep Autoencoder
Pankaj Raj Roy, Guillaume-Alexandre Bilodeau
In this paper, we focus on the development of a method that detects abnormal trajectories of road users at traffic intersections. The main difficulty with this is the fact that the…
