Phase-only Correlation in Human Iris Database

This paper presents human eye-iris registration and matching in an iris database using phase-only correlation techniques. Two modified phase-only correlation techniques with efficient registration results are used: the rectangle band limited phase-only correlation method (BPOC) and an elliptic limited phase-only correlation method (EPOC) the last one being proposed by the authors. The results of the computer simulations obtained for these two methods are analyzed on the same iris database and the analysis denotes that the proposed method EPOC has better performances than BPOC method for iris matching in the used database.
