摘要
在人脸图像定位的前提上,利用灰度信息实现了人脸面部主要器官如眼睛、鼻子和嘴巴的定位。采用双三次插值法对图像进行旋转和缩放。另外,采用直方图增强的方法对图像灰度值进行归一化处理。
On the premise of face location,this paper apply the grey-scale information to locate major facial organs,such as eyes,nose and mouth.Bi-cubic interpolation,needs to be introduced in image rotation and zoom during the preprocessing phase of face images;moreover,grey value of the image is normalized by adopting histogram enhancement.
