| Abstract: | Iris recognition is a noninvasive technique for human identification.In this paper,the current iris location al-gorithms are studied and have been made betterments according to their limitations.A new iris location approach com-bining geometry location and gray gradient edge detection is presented to increase the speed of iris location greatly.The experiment results show that the approach is good to the speed of iris location and robust. |
