Phase Correlation Based Iris Registration Model [Return]
Iris recognition is one of the most reliable personal identification methods. In iris recognition systems, image
registration is an important component. Accurately registering iris images leads to higher recognition rate for an
iris recognition system. This paper proposes a phase correlation based method for iris image registration with
sub-pixel accuracy. Compared with existing methods, it is insensitive to image intensity and can compensate to a
certain extent the non-linear iris deformation caused by pupil movement. Experimental results show that the
proposed algorithm has an encouraging performance.
