Abstract
(EN)
Disclosed techniques relate to identifying subjects in digital images. In various embodiments, a first camera (276, 376, 476, 976) may acquire (1002) digital images (420) depicting a subject in an area. Portion(s) of the digital image(s) that depict a face of the subject may be detected (1004) as detected face image(s). Features of the detected face image(s) may be compared (1006) with features of subject reference templates associated with subject(s) in a subject reference database (412). The subject reference database stores subject reference templates that are associated with multiple subjects and that are generated based on data received from a second camera (256, 456). Based on the comparing, an identity of the subject may be determined (1014) and the features of the detected face image(s) may be stored (1016) in the subject reference database in association with the subject, e.g., as an auxiliary template feature vector for later use.

L'invention concerne des techniques se rapportant à l'identification de sujets dans des images numériques. Dans divers modes de réalisation, une première caméra (276, 376, 476, 976) peut acquérir (1002) des images numériques (420) représentant un sujet dans une zone. Une ou plusieurs parties de l'image ou des images numériques qui représentent un visage du sujet peuvent être détectées (1004) en tant qu'une ou plusieurs images de visages détectées. Les caractéristiques de l'image ou des images de visages détectées peuvent être comparées (1006) avec les caractéristiques des modèles de référence de sujets associés à un ou plusieurs sujets donnés dans une base de données de référence de sujets (412). La base de données de référence de sujets stocke des modèles de référence de sujets qui sont associés à de multiples sujets et qui sont générés d'après les données reçues d'une seconde caméra (256, 456). D'après la comparaison, une identité du sujet peut être déterminée (1014) et les caractéristiques de l'image ou des images de visage détectées peuvent être stockées (1016) dans la base de données de référence de sujets en association avec le sujet, par exemple sous la forme d'un vecteur de caractéristiques de modèle auxiliaire en vue d'une utilisation ultérieure.
