An Algorithm Based on Circle Geometrical Characteristic for Iris Location
Chen Yang · Journal of Logistical Engineering University · 2010
Iris location is a basal procession in an iris recognition system.The speed and accuracy of the iris location decide the performance of the iris recognition system.In order to fasten the speed of iris location,this paper introduces a fast location algorithm for pupil detecting based on the geometrical characteristic of circle.Using the coupling relationship between the inner and outer edges of the iris image,the search range of calculus method to locate outer boundaries is greatly reduced.Experiments show that the algorithm is fast,accurate and robust compared with classical methods.
