Please look at attachment video at the first. don't bid before look at video file.
I am going to build simple windows application. I can provide you face recognization api.
Let me explain the logic of this application.
1. As you can see in the video , the people stands in front of computer which has usb camera.
2. The application detect the person using OpenCV or other library .
3. If the application detect the person , and take a image from usb camera and upload image via face recognization api to get some of users information.
4. show this information on application like video.
I focus on ui part more. i need exactly same as video.
