Iris recognition emerges as one of the most useful modalities for biometrics recognition in last few decades. The goal of iris recognition is to recognize human identity through the textural characteristics of one’s iris muscular patterns. The procedures for iris recognition usually consist of four stages: image acquisition, iris segmentation, feature extraction, and pattern matching. The iris recognition has been acknowledged as one of the most accurate biometric modalities because of its high recognition rate. It has been applied in the field of border control and national security. More and more countries and private companies have shown interests to use the technique of iris recognition. Large scale application of iris recognition in daily life is just a matter of time.


The goal of biometric recognition is to recognize human identity by comparing the features of their physiological or behavioral characteristics. There are dozens of...
