Title (EN) IRIS RECOGNITION SYSTEM, IRIS RECOGNITION METHOD, AND STORAGE MEDIUM
(FR) SYSTÈME DE RECONNAISSANCE D'IRIS, PROCÉDÉ DE RECONNAISSANCE D'IRIS ET SUPPORT D'INFORMATIONS
Abstract:
(EN) An example embodiment includes: a determination unit that, based on an image including an eye of a recognition subject, determines whether or not a colored contact lens is worn; and a processing unit that, when it is determined by the determination unit that the colored contact lens is worn, performs a process of improving accuracy of iris matching on the recognition subject.
(FR) Un mode de réalisation donné à titre d'exemple comprend : une unité de détermination qui, sur la base d'une image comprenant un œil d'un sujet de reconnaissance, détermine si une lentille de contact colorée est portée ou non; et une unité de traitement qui, lorsqu'il est déterminé par l'unité de détermination que la lentille de contact colorée est portée, réalise un traitement d'amélioration de la précision de mise en correspondance d'iris sur le sujet de reconnaissance.
