Abstract

Il est décrit un système et une méthode de suivi dobjets dans une scène dune séquence dimages captées par un imageur. La méthode comprend le traitement de la séquence dimages pour générer des images séquentielles à une pluralité de niveaux hiérarchiques pour générer un ensemble de régions dintérêt; et, à chacun des niveaux hiérarchiques : examiner des paires dimages séquentielles pour relier des pixels dans des pistes courtes; et grouper les pistes courtes qui indiquent des modèles de mouvement semblables pour générer des pistes représentatives. Les pistes représentatives sont groupées pour générer un résultat de suivi pour au moins un objet.
