A Fast Iris Location Method
Wang Jinfang · Journal of Hunan International Economics University · 2007
Aiming at the localization of iris location algorithm,a new iris location algorithm is presented.Firstly, the number of iris image grey-scales that are less than a threshold value is counted at y-axis or x-axis.The pupil cen- ter,length and short half axis are located with the most continuum connect section at quarter of the most value apiece.The facla and eyewinker infection could be licked by this method.Using the pupil center locating parameters,the outer edge of the iris image is located with circumfluence integral at 5 pels between the iris center and the pupil centers and θ is limited in the scale(-45°,45°)∪(135°,225°).The eyelid and eyewinker disturbance could be avoided by this method. The result shows that this method can improve the speed of locating the iris edges and improve the speed.
