IRIS CODE GENERATION METHOD, INDIVIDUAL AUTHENTICATION METHOD, IRIS CODE ENTRY DEVICE, INDIVIDUAL AUTHENTICATION DEVICE, AND INDIVIDUAL CERTIFICATION PROGRAM

摘要

An iris image is obtained by inputting a plurality of images captured by imaging the same eye (S11) and cutting out an iris area (S12). Moreover, a single iris image is obtained (S15) by transforming the coordinate system of the iris images from the rectangular coordinate system to the polar coordinate system (S13), applying rotation compensation (S14), and adding the pixel values while weighting the pixel values for each polar coordinate. An iris code is generated from the obtained single iris image (S16 and S17).
