| 摘 要： | 以椭圆形来定义瞳孔,提出了一种计算瞳孔特征参数的方法.用椭圆上的两对点确定椭圆的中心、旋转角度、长半轴、短半轴等参数.实验表明,该方法速度快,检测性能好,可以通过非连续的边缘确定椭圆的参数.最后,比较了该算法确定的椭圆形瞳孔边缘与其它边缘检测算法得到的瞳孔边缘.

| Abstract: | Define pupil as ellipse,a algorithm is presented to determine the parametric characterization of pupil.Two pairs of point on the ellipse are used to determine the location of the center of the ellipse,orientation,and the two semi-axis.Extensive experimental results show that the proposed algorithm is capable of detecting ellipse feature with an excellent accuracy and efficiency.It can obtain the parameter of ellipse through discontinuous edge. And last,comparisons between proposed algorithm and other approaches for edge detection are presented. |
