摘　　要：笔者在此提出了一种基于灰度信息和Harris角点检测的眼睛特征提取算法,首先利用眼睛区域的灰度信息,提取出瞳孔的位置和大小,然后利用Harris角点检测算法找到眼角点,最后利用曲线拟合算法拟合出眼睛的轮廓。结果表明Harris角点检测能够有效地提取眼睛特征。Eye feature extraction algorithm based on gray information and Harris comer detection is presented. This method locates the eye areas roughly in the facial sub-image firstly,then locates the pupil areas accurately in the eye areas fixed on the previous step by gray statistical information,and finds out the eye comers through Harris comer detection. Finally,the outline of eye is fitted by using B-spline curves through the detected key points. Experiment shows that eye feature can be extracted effectively based on Harris comer detection.
