代码说明:

    本函数选用阈值分割的方法来完成瞳孔定位。根据图像的灰度分布特性,瞳孔部分的灰度值最小,其次为虹膜部分,最大的为巩膜部分。因此在灰度直方图中,第一个大峰值的邻域即是瞳孔所在区域。(Function selects the threshold segmentation method to accomplish the pupil location. Based on image gray distribution features, the pupil part of the grey value of the minimum, followed by the iris part, the biggest part of sclera. So in gray level histogram, the peak value of the first big neighborhood is the pupil area.)
