1) face center
人脸中心点
2) Nature face
中性人脸
3) face feature points
人脸特征点
1.
In this paper,the improved method of active shape model is used to extract face feature points accurately,then a coarse estimation value is obtained by using face feature points,and takes this coarse value as the starting value,precise value of 3D face pose is obtained based on linear regression iteration.
改进传统的活动形状模型法,准确地提取人脸特征点后,利用人脸特征点初步估计人脸姿态,以初步估计值为初始值,通过线性回归迭代算法,精确估计3D人脸空间姿态。
4) geometrical characteristics of human face
人脸几何特点
1.
Firstly,the eye area is identified from the face image based on the curves of gray-level projection and geometrical characteristics of human face;then the obtained eyes area is compared with the preparative eye template to judge whether the eye is closed or not.
首先基于灰度投影曲线和人脸几何特点提取驾驶员的眼部区域,然后利用事先提取的驾驶员睁眼时的瞳孔区域模板在该区域进行匹配,通过匹配初步判断出驾驶员是否属于疲劳驾驶。
补充资料：一个中心，两个基本点
党的基本路线的核心内容。一个中心，指以经济建设为中心；两个基本点，指坚持四项基本原则，坚持改革开放。1987年中共十三大作出这一概括。参见“党的基本路线”(1011页)。
