(FR) SYSTÈMES ET PROCÉDÉS D'IDENTIFICATION DE CIBLE DANS UNE VIDÉO
Abstract
(EN)
The present disclosure relates to systems and methods for target identification in a video. The method may include obtaining a video including a plurality of frames of video data. The method may further include sampling, from the plurality of frames, each pair of consecutive sampled frames being spaced apart by at least one frame of the plurality of frames of the video data. The method may further include identifying, from the one or more sampled frames, a reference frame of video data using an identification model. The method may still further include determining a start frame and an end frame including the target object.

La présente invention concerne des systèmes et des procédés d'identification de cible dans une vidéo. Le procédé consiste à : obtenir une vidéo comprenant une pluralité de trames de données vidéo ; effectuer un échantillonnage dans la pluralité des trames, chaque paire de trames consécutives échantillonnées étant espacée par au moins une trame de la pluralité des trames des données vidéo ; identifier, dans la ou les trame(s) échantillonnée(s), une trame de référence de données vidéo à l'aide d'un modèle d'identification ; déterminer en outre une trame de début et d'une trame de fin comprenant l'objet cible.
