读入图像序列，从图片中定位人脸，按输入要求尺寸抓取人脸，并可通过尺寸归一、灰度归一处理图像，进而实现对图像序列的表情识别

基于matlab开发的截屏软件，可方便抓取屏幕并保存为图片。-Matlab based software development screenshots, can easily fetch the screen and save it as a picture.

人脸识别 视频与图片中的人脸抓取 跟踪 锁定-for the image recoginazation

采用tensorflow的深度学习框架，采用opencv，采用时间戳，和特征抓取，自动抓取图片特征，然后存储(Using tensorflow's deep learning framework, opencv, timestamp, and feature capture are used to automatically capture image features, and then store them)
