本程序实现人脸对齐功能，它通过提取人脸特征，利用PCA降维，实现人脸对齐效果-This program implements the face alignment feature, it is through facial feature extraction using PCA dimensionality reduction to achieve the effect of face-aligned

本程序通过自动编码网络实现实时的人脸对齐，运行时需要添加opencv的d-This program automatically encoded by the network for real-time face-aligned, you need to add the runtime dll opencv
