A brief review of the iris recognition systems for developing a user-friendly biometrie application

A biometric system offers automatic identification of a human being based on the unique feature or characteristic which is being possessed by the individual. A number of biometric techniques exists in the current scenario, viz., finger print, iris, face, etc. The iris segmentation is one of the most dominant type used in all Aadhar card applications & has its own major applications in the field of surveillance as well as in security purposes. The performance of the iris recognition systems depends heavily on the feature extraction, histogram, and segmentation with normalization techniques. In this survey paper, a brief review of the research work done in the field of iris recognition systems is presented, i.e., in the sense a review of various iris recognition approaches used in iris recognition is done in this paper & is represented in a concise form for quick reference.
