Patent

CA 2569440

Methods and systems are provided for performing a biometric measurement on an individual. A purported skin site of the individual is illuminated under a plurality of distinct optical conditions during a single illumination session. Light scattered beneath a surface of the purported skin site is received separately for each of the plurality of distinct optical conditions. A multispectral image of the purported skin site is derived from the received light. A biometric function is performed with the derived multispectral image.

Procédés et systèmes pour mesure biométrique sur un individu. On illumine un site de peau spécifique sous plusieurs conditions optiques distinctes durant une session d'éclairage unique. La lumière diffusée sous une surface de ce site est reçue séparément pour chacune des conditions. On dérive une image multispectrale de la lumière reçue, puis une fonction biométrique est conduite sur la base de cette image.
