Review of IRIS recognition techniques

Iris recognition is effective biometric technique that gained attention in past 20 years. Over past few years many techniques and algorithms are proposed for effective iris recognition under various constraints. Low constraint IRIS recognition is still an area where considerable work needs to be done and there is huge scope to do. This paper discusses about various techniques proposed, the constraints in which they are suitable for is studied and summarized It also discusses on the issues affecting the recognition accuracy. In our implementation we are proposing some novel methods to overcome the factors adversely affecting the iris recognition accuracy.
