![]() Histogram equalization technique is used to enhance the normalized iris image contrast. Rubber Sheet Model is used as an unwrapping and normalization algorithm. Canny edge detector and Circular Hough Transform are used to localize the iris region. Threshold concepts areused to segment the pupil. To overcome the problems of obtaining a real-time decision of the human iris in an accurate, robust, low complexity, reliable, and fast technique. Iris recognition system is, implemented in software. ![]() General Purpose Systems are low speed and not portable FPGA-based system prototype implemented by using VHDL language. Pattern recognition approaches suffer from high cost, long development times, and computationally intensive. Iris is touch-less automated real-time biometric system for user authentication.
