title: how image processing detect photograph or real person in front of camara?
body: <p>I planned to develop a software that can takes attendant (work , school) by face recognition as my final year project(FYP).(Just an Idea)</p>
  
  <p>I have search through the net about the image processing library and i found out <code>OpenCv</code> is more well known as i found a lot of video for face recognition using <code>OpenCv</code> in youtube which will definitely help me a lot.(I'm totally new to image processing). Also, i will be using Visual Studio.</p>
  
  <p>Here come the first problem, which is is it possible to detect that it is a photo or a real person is standing in front of the camera while taking the attending?</p>
  
  <p>If yes, can you provide me some link or tutorial link for how image processing can detect 'photograph' and 'real person'?</p>
  
  <p>As i said, I'm totally new to image processing and this is just an idea for my FYP</p>
  
  <p>Or is the any open sources library that you recommend? </p>
