Title (EN) GLINT DETECTION METHOD
(FR) PROCÉDÉ DE DÉTECTION DE REFLET
(KO) 글린트 검출 방법
Abstract:
(EN) A glint detection method is disclosed. A glint detection method, according to one embodiment of the present invention, relates to a method for detecting a glint from an iris image, which is photographed prior to an authentication procedure, by using an iris image of a human body. In addition, the glint detection method according to one embodiment of the present invention removes, in advance, the iris image, in which the user authentication cannot be performed due to the glint, thereby increasing a recognition rate and reducing an error rate.
(FR) L'invention concerne un procédé de détection de reflet. Un procédé de détection de reflet, selon un mode de réalisation de la présente invention, se rapporte à un procédé de détection d'un reflet à partir d'une image d'iris, qui est photographiée avant une procédure d'authentification, en utilisant une image d'iris d'un corps humain. De plus, le procédé de détection de reflet selon un mode de réalisation de la présente invention élimine, à l'avance, l'image d'iris, dans laquelle l'authentification de l'utilisateur ne peut pas être effectuée en raison du reflet, ce qui permet d'augmenter le taux de reconnaissance et de réduire le taux d'erreur.
(KO) 글린트 검출 방법이 개시된다. 본 발명의 일 실시예에 따른 글린트 검출 방법은, 사람의 홍채 이미지를 이용하여 인증 절차를 수행하기에 앞서 촬영된 홍채 이미지에서 글린트를 검출하는 방법에 관한 것이다. 또한, 본 발명의 일 실시예에 따른 글린트 검출 방법은 글린트로 인해 사용자 인증이 불가능한 홍채 이미지를 사전에 제거하여 인식률은 높이고 에러율을 낮출 수 있도록 한다.
