Abstract
Despite significant progress made in iris recognition, handling noisy and degraded iris images is still an open problem and deserves further investigation. This paper proposes a feature extraction method to cope with degraded iris images. This method is founded on applying the 2D-wavelet transform on overlapped blocks of the iris texture. The proposed approach enables us to select the most informative wavelet coefficients providing both essential texture information and enough robustness against the degradation factors. Our experimental results on the UBIRIS database demonstrate the effectiveness of the proposed method that achieves 4.10%FRR (@ FAR=.01 %) and 0.66% EER.
