An event detection method for video surveillance systems and a related video surveillance system are described. The method comprises a learning phase, wherein learning images of a supervised area are acquired at different time instants in the absence of any detectable events, and an operating detection phase wherein current images of said area are acquired. The method detects an event by comparing a current image with an image corresponding to a linear combination of a plurality of reference images approximating, or coinciding with, respective learning images.

L'invention concerne un procédé de détection d'événements pour systèmes de surveillance vidéo, ainsi qu'un système de surveillance vidéo apparenté. Le procédé comprend une phase d'apprentissage, au cours de laquelle des images d'apprentissage d'une zone surveillée sont acquises à différents instants dans le temps en l'absence d'événements détectables, et une phase de détection fonctionnelle au cours de laquelle les images actuelles de ladite zone sont acquises. Le procédé détecte un événement en comparant l'image actuelle à une image correspondant à une combinaison linéaire de plusieurs images de référence représentant une approximation des images d'apprentissage respectives ou coïncidant avec celles-ci.
