A Method for the Identification of Noisy Regions in Normalized Iris Images
In this paper we propose a new method for the identification of noisy regions in normalized iris images. Starting from a normalized and dimensionless iris image in the polar coord...

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...
