Predicting Next Local Appearance for Video Anomaly Detection
Pankaj Raj Roy, Guillaume-Alexandre Bilodeau, Lama Seoud
We present a local anomaly detection method in videos. As opposed to most existing methods that are computationally expensive and are not very generalizable across different video…

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…
