Study on stable reliability problem of problem recognition,iris recognition is a recently emerging biological identification method,has simple algorithm,fast recognition and high recognition rate characteristics.To change the traditional way's instability,this paper proposed a iris recognition algorithm.Firstly,using coarse positioning and precision positioning method to combine the pupil center and radius location to position iris inner boundary,coarse is positioned by iris external boundary non collinear the 3 point round 1 to avoiding the iris location searching blindness,reduces the computation time and reduce the complexity of positioning,then by using Hough transform for iris for fine positioning and Gabor filter is used for iris feature extraction,finally using the Hamming distance iris matching.The simulation results show that,compared with other identity recognition algorithm,the proposed algorithm has improved the recognition rate and minim the computational complexity.
