title: Real time face detection using Viola and Jones in MATLAB
body: <p>I am looking to detect faces in real time video captured from laptop camera. I use MATLAB R2011a (not the latest one) which does not have any Cascade Object Classifier function to identify face detection.</p>
  
  <p>I have used a package <a href="http://www.mathworks.in/matlabcentral/fileexchange/29437-viola-jones-object-detection" rel="nofollow">http://www.mathworks.in/matlabcentral/fileexchange/29437-viola-jones-object-detection</a></p>
  
  <p>This code is able to identify modestly on images but when I do the same on video's (taking each frame and identify face in it) its taking lots of time and thus not able to stream video.</p>
  
  <p>So,</p>
  
  <ol>
  <li>How should I able to detect faces real time using MATLAB R2011a</li>
  <li>Is viola &amp; jones algorithm suitable for it?</li>
  <li>Are there any external implementations that I can use?</li>
  </ol>
