Look at Adjacent Frames: Video Anomaly Detection without Offline Training

no code implementations27 Jul 2022 Yuqi Ouyang, Guodong Shen, Victor Sanchez

Based on the information shifts between adjacent frames, an incremental learner is used to update parameters of the multilayer perceptron after observing each frame, thus allowing to detect anomalous events along the video stream.

Video Anomaly Detection by Estimating Likelihood of Representations

1 code implementation2 Dec 2020 Yuqi Ouyang, Victor Sanchez

Video anomaly detection is a challenging task not only because it involves solving many sub-tasks such as motion representation, object localization and action recognition, but also because it is commonly considered as an unsupervised learning problem that involves detecting outliers.
