该程序是通过摄像头实时检测红色目标，并且标记，计算出质心坐标，请在运行之前确保matlab安装了相应的摄像头驱动-The program is through the camera in real-time detection of the red target, and Mark, the calculated centroid coordinates, make sure before running matlab installed the appropriate camera drive

用于人脸识别，检测驾驶员人员是否疲劳，在现实中有很好的应用，其算法简单易懂，适合初学者(For face recognition, detection of driver fatigue, in reality has a very good application, the algorithm is simple, easy to understand, suitable for beginners)
