IRIS biometrics survey 2010–2015

This paper gives a survey on Iris Biometric recognition technique for past few years. Iris is one of the most promising, reliable, and robust biometric technology. In this paper, advancements in research methodologies used by different researchers for iris localization, iris segmentation, feature extraction, and classification are discussed. The limitations of existing algorithms and their results are also discussed. We also discussed here, existing difficulties in iris biometric, possible solutions on them, and future scope in this field. The vast progress in this field shows that iris biometric still needs fast, real time, reliable, and robust algorithms so as to have higher recognition rate and better accuracy. We hope that this paper will surely increase interest of new researchers towards this area with new opportunities and challenges.
