A REVIEW ON VARIOUS IRIS RECOGNITION TECHNIQUES IN BIOMETRICS

The iris recognition is a kind of the biometrics technologies based on the physiological characteristics of human body, compared with the feature recognition based on the fingerprint, palm print, face and sound etc, the iris has some advantages such as uniqueness, stability, high recognition rate, and non infringing etc. The iris recognition consists of iris localization, normalization, encoding and comparison. Iris recognition is an automated method of biometric identification that uses mathematical pattern - recognition techniques. In this paper we have presented a review on various techniques in iris recognition
