Enhancement of Iris Recognition System Based on Phase Only Correlation
Abstract: Iris recognition
system is one of biometric based recognition/identification systems. Numerous
techniques have been implemented to achieve a good recognition rate, including
the ones based on Phase Only Correlation (POC). Significant and higher
correlation peaks suggest that the system recognizes iris images of the same
subject (person), while lower and unsignificant peaks correspond to recognition
of those of difference subjects. Current POC methods have not investigated
minimum iris point that can be used to achieve higher correlation peaks. This
paper proposed a method that used only one-fourth of full normalized iris size
to achieve higher (or at least the same) recognition rate. Simulation on CASIA
version 1.0 iris image database showed that averaged recognition rate of the
proposed method achieved 67%, higher than that of using one-half (56%) and full
(53%) iris point. Furthermore, all (100%) POC peak values of the proposed
method was higher than that of the method with full iris points.
