title: How to do realtime face detection?
body: <p>how can I realize realtime face detection, when I use iPhone camera to take picture? </p>
  
  <p>just like the example: <a href="http://www.morethantechnical.com/2009/08/09/near-realtime-face-detection-on-the-iphone-w-opencv-port-wcodevideo/" rel="nofollow">http://www.morethantechnical.com/2009/08/09/near-realtime-face-detection-on-the-iphone-w-opencv-port-wcodevideo/</a> (this example don't provide the .xcodeproj, so I can't compile .cpp file)</p>
  
  <p>another example: <a href="http://blog.beetlebugsoftware.com/post/104154581/face-detection-iphone-source" rel="nofollow">http://blog.beetlebugsoftware.com/post/104154581/face-detection-iphone-source</a>
  (can't be compiled)</p>
  
  <p>do you have any solution? please give a hand!</p>
