【Abstract】 An algorithm is proposed, which locates pupillary boundary and iris center based on standard deviation leading to fast location of the outer boundary. The experimental results indicate that this method can speed iris location, and improve stability of iris location. It also reduces blindness in search of the original method.更多还原
