该程序用于照片的归一化和瞳孔对准。

其中ImageRotate函数用于将偏转的头像转正，用于歪头的情形，转头的情形不适合。

ImageZoom函数将照片变得与基准照片一个尺度，即所有照片的瞳孔间距与基准照片的瞳孔间距相同。

ImageAlign函数用于对准瞳孔，通过偏移，将所有照片的瞳孔位置变得与基准照片的瞳孔位置一致。-　This procedure for photos normalized and pupil alignment.　 For the deflection Avatar ImageRotate function regularization for the case of head tilt, turned around the situation is not suitable.　 ImageZoom function photo becomes a measure of the reference photo, all photos pupil spacing pupil spacing the same reference photo.　 ImageAlign function is used to align the pupil, through the offset, all pictures in the pupil position becomes consistent with the pupil position of the reference photo.
