Scene and crowd behaviour analysis with local space-time descriptors
Marco Bertini, Alberto Del Bimbo, Lorenzo Seidenari · 2012
In this paper we propose a local space-time descriptor to be employed for behaviour analysis in video-surveillance applications. We show how this local video representation is able to extract scene semantics in both a supervised (behaviour recognition) and semi-supervised (anomaly detection) setup. Our approach yields state-of-the art performance on two publicly available datasets and is not computationally intensive.
