中文说明：旋转图像的全局配准技术最早是由 Johnson提出，在曲面上划分三角形有限元网格， 在每个节点上分别计算一个旋转图像。 旋转图像法的最大优点在于，随着计算旋转图像时选取的节点数目由少到多， 旋转图像逐步由局部特征演变为全局特征，也就是说旋转图像可以描述一定区域内的曲面形状。而对于有特别的几何形状的点（鼻尖、眼角点等），能形成非常特殊的旋转图像。 (参考文献：三维人脸特征点定位技术研究)
English Description：
Rotate image global registration of technology was first put forward by Johnson, Division of triangular finite element mesh on the surface, calculated separately on each node in a rotated image. Rotate the image by its biggest advantage is that, as the number of rotating images when selected node from less to more, rotate the image gradually by local characteristics into global features, meaning that rotates the image to describe the shape of surfaces within a certain area. But for the Special geometry of the point (nose, eyes, etc) and can form a very special rotating images. (Reference: research on three dimensional facial feature point location)
