Title
(EN) METHOD AND SYSTEM FOR DETECTING MOVING OBJECTS
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT DE DÉTECTER DES OBJETS EN MOUVEMENT
Abstract
(EN) A moving objects detection method is disclosed. The method may include: identifying a plurality of feature points based on a plurality of video frames; selecting from the plurality of feature points to form a first and a second groups of feature points based on correlations between the plurality of feature points; and identifying in at least one video frame two segments based on the first and the second groups of feature points, respectively, as detected moving objects, where a correlation between two feature points may include a distance component and a movement difference component, where the distance component is related to a distance between the two feature points, and the movement difference component is related to a difference between corresponding movements of the two feature points. A moving objects detection system is also provided.
(FR) La présente invention concerne un procédé de détection d'objets en mouvement. Le procédé peut consister à : identifier une pluralité de points de caractéristiques sur la base d'une pluralité de trames vidéo; effectuer une sélection dans la pluralité de points de caractéristiques pour former un premier et un second groupe de points de caractéristiques sur la base des corrélations entre la pluralité de points de caractéristiques; et identifier dans au moins une trame vidéo deux segments sur la base du premier et du second groupe de points de caractéristiques, respectivement, comme étant des objets en mouvement détectés, une corrélation entre deux points de caractéristiques pouvant comprendre un composant de distance et un composant de différence de mouvement, le composant de distance étant lié à une distance entre les deux points de caractéristiques, et le composant de différence de mouvement étant lié à une différence entre des mouvements correspondants des deux points de caractéristiques. L'invention concerne également un système de détection d'objets en mouvement.
