This paper presents an iris coding method for effective recognition of an individual. The recognition is performed based on a mathematical and computational method called discrete cosine transform (DCT). It consists of calculating the differences of discrete cosine transform (DCT) coefficients of overlapped angular patches from the normalized iris image for the purpose of feature extraction. DCT is used because it offers efficiency, it is much more practical and its basis vectors are comprised of entirely real-valued components.
