Title (EN) DETAILED EYE SHAPE MODEL FOR ROBUST BIOMETRIC APPLICATIONS
(FR) MODÈLE DÉTAILLÉ DE FORME D'ŒIL POUR APPLICATIONS BIOMÉTRIQUES ROBUSTES
Abstract:
(EN) Systems and methods for robust biometric applications using a detailed eye shape model are described. In one aspect, after receiving an eye image of an eye (e.g., from an eye- tracking camera on an augmented reality display device), an eye shape (e.g., upper or lower eyelids, an iris, or a pupil) of the eye in the eye image is calculated using cascaded shape regression methods. Eye features related to the estimated eye shape can then be determined and used in biometric applications, such as gaze estimation or biometric identification or authentication.
(FR) L'invention concerne des systèmes et des procédés d'applications biométriques robustes utilisant un modèle détaillé de forme d'œil. Selon un aspect, après avoir reçu une image d'œil d'un œil (p. ex. en provenance d'une caméra de suivi d'œil sur un dispositif d'affichage à réalité augmentée), une forme d'œil (p. ex. paupières supérieure ou inférieure, iris ou pupille) de l'œil figurant sur l'image d'œil est calculée à l'aide de procédés de régression de forme en cascade. Des caractéristiques oculaires liées à la forme d'œil estimée peuvent alors être déterminées et utilisées dans des applications biométriques, telles qu'une estimation du regard, ou une identification ou une authentification biométrique.
