Title (EN) LOW FALSE ALARM RATE VIDEO SECURITY SYSTEM USING OBJECT CLASSIFICATION
(FR) SYSTEME DE SECURITE VIDEO A FAIBLE TAUX DE FAUSSES ALERTES UTILISANT LA CLASSIFICATION D'OBJETS
Abstract:
(EN) A video detection system (10) and method detects an intruder from video images of a scene. The method employs a recognition process to differentiate between humans and animals. The method is used only after possible false alarms resulting from identified effects of noise, aliasing, non-intruder motion occuring within the scene, and effects of global or local lighting changes. The object recognition process includes determining the regions containing a potential intruder, outlining and growing those regions to encompass all of potential intruders, determining a set of shape features from the region and eliminating possible shadow effects, normalizing the set, and comparing the normalized set with sets of features of humans and animals. This comparison produces a confidence level indicating a human intruder. An alarm is given for a sufficiently high confidence level. The possibility of a false alarm due to an animal or a non-identifiable object is also substantially eliminated.
(FR) L'invention se rapporte à un système de détection vidéo (10) et à un procédé destiné à détecter la présence d'un intrus par les images vidéo d'un lieu. Le procédé utilise un procédé de reconnaissance qui permet de faire la différence entre les êtres humains et les animaux. Le procédé n'est mis en application qu'après d'éventuelles fausses alertes résultant de l'identification de bruits, de distorsions, de mouvements effectués par des non-intrus et des effets de changements de lumière complets ou locaux. La reconnaissance d'objets comprend la détermination des endroits où se trouve un intrus éventuel, la vision générale et l'agrandissement desdits endroits de façon à englober tous les intrus éventuels, la détermination d'un ensemble de formes en provenance de cet endroit et l'élimination d'effets d'ombre éventuels, la normalisation de l'ensemble et la comparaison des formes normalisées avec des caractéristiques humaines ou animales. La comparaison offre un niveau fiable de reconnaissance d'un intrus humain. Si le degré de fiabilité est suffisant, l'alerte est donnée. Ainsi, les risques de fausses alertes dérivées de la présence d'un animal ou d'un objet non identifiable sont pratiquement inexistants.
