Iris location algorithm based preconditioning voting
Zhihui Li · Journal of Jilin University · 2009
Traditional iris location algorithms that have drawbacks of slow locating and partial occlusion influences such as eyelids,eyelashes and so on,the paper presented a preconditioning voting circle detection algorithm based on preconditioning voting and circle geometry property.In additional,in order to reduce the computation and effect by partial occlusion,such as eyelid,eyelashes etc,the iris boundaries are localized,using a coarse-to-fine strategy,in regions of interest.In experiments,the proposed method is compared with the integral-differential operator and Hough transform algorithm based on JLU-IRIS iris database.From the experiment results,the proposed method is faster and better than the other two methods.
