Title (EN) BIOMETRIC FEATURE DATABASE ESTABLISHING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL D'ÉTABLISSEMENT DE BASE DE DONNÉES DE CARACTÉRISTIQUES BIOMÉTRIQUES
Abstract:
(EN) A usage frequency attribute of each biometric feature in a biometric feature database is obtained. An indication is generated of matching success frequency of the biometric feature based on the usage frequency attribute. The biometric features are arranged in descending order of matching success frequency based on the usage frequency attribute. Recognition of a user is performed based on one of the biometric features having a higher frequency.
(FR) L’invention concerne l'obtention d'un attribut de fréquence d'utilisation de chaque caractéristique biométrique dans une base de données de caractéristiques biométriques. Une indication de la fréquence de réussite correspondante de la caractéristique biométrique est générée sur la base de l'attribut de fréquence d'utilisation. Les caractéristiques biométriques sont agencées par ordre décroissant de fréquence de réussite correspondante sur la base de l'attribut de fréquence d'utilisation. La reconnaissance d'un utilisateur est effectuée sur la base de l'une des caractéristiques biométriques ayant une fréquence supérieure.
