中文说明：将人脸a变换到人脸b求出过渡图片c，即morph，这个是基于人脸特征提取的matlab编程。在一张人脸上提取两个点确定一条线。若干条线标记既可以构成一张人脸地图。这个在图像重建中的矩阵变换有着重要的作用
English Description：
Transform face a to face B to get the transition picture C, that is morph. This is matlab programming based on face feature extraction. Two points are extracted from a face to determine a line. Several line markers can form a face map. This matrix transformation plays an important role in image reconstruction
