A method for providing orientation independent face detection may include generating multiple mosaic images from an input image in which each of the multiple mosaic images has a different scale, employing a plurality of differently oriented edge detectors to perform edge detection on the multiple mosaic images including combining edges of the multiple mosaic images having the different scales, and performing face detection in regions corresponding to the differently oriented edge detectors based on respective feature maps produced by the differently oriented edge detectors. An apparatus and computer program product corresponding to the method are also provided.

La présente invention concerne un procédé permettant fournir la détection de visages indépendante de lorientation comprenant la génération dune pluralité dimages en mosaïque à partie dune image saisie dans laquelle chacune de la pluralité dimages en mosaïque présente une échelle différente, lutilisation dune pluralité de détecteurs de contours orientés pour effectuer une détection de contours sur la pluralité dimages en mosaïque comprenant la combinaison des contours de la pluralité dimages en mosaïque ayant différentes échelles, et la réalisation de détection de visages dans des régions correspondant aux détecteurs de contours à orientation différente sur la base de cartes de traits respectifs produits par les détecteurs de contours orientés à orientation différente. Linvention concerne également un appareil et un programme dordinateur correspondant au procédé selon linvention.
