摘要
提出一种根据标准偏差定位瞳孔边缘和圆心 ,从而快速定位虹膜外边缘的方法 .试验结果表明 ,提出的方法提高了虹膜定位的速度以及定位的稳定性 。
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.
