Long Distance Iris Recognition

In this paper we introduce an algorithm to analyzethe human iris, long-range iris recognition software has beendeveloped to be more user-friendliness and create an economicway to the identification. Our algorithm centralized on pupildetection, and by using estimated ranges we omit the otherregions to create more efficient search space. The final decisionon iris region detection provides by Hough Transform. We usethe Gaussian method to create a refined mask which has animportant rule of the matching process. To extract efficientfeatures of iris regions and matching we used SIFT algorithm,Results on CASIAV4-at Distance shows %93 as verification Rate
