Iris Recognition: An Entropy-Based Coding Strategy Robust to Noisy Imaging Environments
Abstract. The iris is currently accepted as one of the most accurate traits for biometric purposes. However, for the sake of accuracy, iris recognition systems rely on good quality...

Binary Morphology and Local Statistics Applied to Iris Segmentation for Recognition
One of the first steps in iris recognition is isolating (or segmenting) the iris from an image of the subject's eye area. This paper investigates new approaches for locating ...
