摘要
提出了一种新的人眼定位方法。使用中值滤波和直方图均衡方法去除噪声和光照对图像的影响后,将图像做积分投影以缩小到人脸的眼部区域,在得到的眉眼区域中再做一次水平积分投影,找到两眼的垂直位置。最后利用人眼模板沿着该垂直方向进行匹配,匹配程度最高的部分即为要定位的人眼位置。
A new method of eye location is presented in this paper. After applying median filter to eliminate the image noise, the gray - level integral projection along the horizontal and vertical direction is used to locate the small area including the eyes in the image. Finally this small area is matched by using eye templates along the vertical direction. If an area satisfies the template mostly, then it must be the location of eyes.
