Iris location algorithm based on line-rank scanning
Luo Xiang · Jisuanji gongcheng · 2004
A new iris location method was promoted. At first, we extracted the inner boundary of iris based on the grey scale and filled in the inner part of the pupil, then got rid of the points out of the pupil based on line-rank scanning, finally obtained the precision location of the center and circle of pupil and iris with least square method.
