Patent abstract
A method of comparing a test iris image with a candidate iris image comprises generating test and candidate lists representative of measured image values along respective curves around the pupils. Treating these list as periodic, a relative displacement is calculated at which one list best matches the other list. This determines the amount of rotation required for best match of the iris images. The method may be used either alone or in combination with other identity verification systems.
