Biometrics system has the potential for application to identification and verification of individuals for controlling access to secured areas, many countries support biometrics research. In this paper localization of the inner and outer boundaries of the iris is done by finding the maximum blurred partial derivative. Normalization of iris has been achieved by projecting the original iris in a cartesian coordinate system into a doubly dimensionless pseudopolar coordinate system. CASIA iris database has been used to test the algorithms.
