碩士 === 元智大學 === 電機工程學系 === 91 === In current technique of the information, security for systems is becoming more and more important. The biometric provides a secure method of recognition, since it is difficult to replicate and steal. In this thesis, we introduce a multi-channel NOJTC method with minimum average cross-correlation energy for polychromatic iris recognition. The system is based on the nonzero order joint transform correlator and uses Lagrange multipliers to design a reference function for polychromatic iris image recognition. Simulation results of the iris recognition show some good performance. Therefore the concept of MACE-NOJTC can be applied for the biometric iris recognition.
