Why Iris? Iris is the best biometric tool for human identification because of its properties of uniqueness, even for a twin. lifetime stability, doesn’t varied with time. Iris semi-circular shape, which leads to easy segmentation method reflecting high recognition rates. Thus, iris recognition is one of the most stable and reliable means in biometric identification. Iris Recognition Algorithm • A classical iris recognition algorithm usually consists of four steps: -Segmentation, -Normalization, -Feature extraction with coding and -Matching. Modification Objects * A one or more of these steps (such as segmentation or feature extraction) can be modified to obtain - ...

Overview The Iris as a Biometrics: The iris is an overt body that is available for remote assessment with the aid of a machine vision system to do automated iris recognition. Iris recognition technology combines computer vision, pattern recognition, statistical inference, and optics. The spatial patterns that are apparent in the human iris are highly distinctive to an individual.
