Some Observations from the Scrutiny of Different Methods used for Iris Recognition

The objective of this work is to determine the ability of methods that are used for iris recognition. Because of unique characteristics of iris recognition have mesmerize more attention of researchers, which make iris identification system development rapidly. In whole process of iris identification various methods are available. Since the techniques which we are considering is the first step of iris image processing, the accuracy and quality of location will directly affect the ultimate results of iris recognition. This paper will summarize the ideas of the existed iris techniques; finally, there is a discussion on some of the challenges encountered by better techniques when operating in a real-world environment and some of the methods used to address these challenges.
