| 摘 要： | 提出了一种人脸图像预处理改进算法:将图片转化为灰度图像后进行去噪滤波,根据灰度投影曲线确定人脸的边界,依据确定的眼、嘴以及脸的左右边界这些参数对图像进行剪裁,根据人脸特征的几何关系确定人脸图像的缩放系数,得到标准化图像.解决了传统方法无法适用于侧脸和双眼闭上的人脸的问题.

| Abstract: | An available method of face image preprocessing has been put forward,in which gray images are median filtered firstly,borderlines are located according to gray level projection of face image.Secondly cropping and zooming of face image have been done according to parameters chosen from the face features.Finally a standardized face image is obtained.It can adapt to profiles and faces with shut eyes. |

| Keywords: | face recognition median filtering vertical gray level projection horizontal gray level projection |
