C++ AND OPENCV PEOPLE IDENTIFIER/DETECTOR

Good morning everyone and thank you for your attention. I have a little done with opencv open source software that detects the faces of people who are in front of the webcam pc. Clicking on a button, the software saves the face and then clicking another button, try to identify the person's face in front of the webcam. What I would like to do is automate the process of saving face with a serial number to a file and then identify in real time all the fccie of all the people who are in front of the webcam. I also want to make sure that the software acquires the video for more 'sources instead of one. This is the link to download the project [login to view URL]
