ADVANCE METHODOLOGY IN IRIS RECOGNITION

Over the years, iris recognition has gained importance in the biometrics applications and is being used in several large scale nationwide projects. Though iris patterns are unique, they may be affected by external factors such as illumination, camera-eye angle, may also pose a challenge to iris biometrics as it obfuscates the iris patterns and changes the inter and intraclass distributions. This paper presents an in-depth analysis of the effect of contact lens on iris recognition performance. The presence of contact lens, particularly color cosmetic lens, However, further research is required to build sophisticated lens detection algorithm that can improve iris recognition.
