title: single person tracking from video sequence
body: <p>As a part of my thesis work, I need to build a program for human tracking from video or image sequence like the <a href="http://www.nada.kth.se/cvap/actions/"><code>KTH</code></a> or <a href="http://4drepository.inrialpes.fr/public/viewgroup/6"><code>IXMAS</code></a> dataset with the assumptions:</p>
  
  <ul>
  <li>Illumination remains unchanged</li>
  <li>Only one person appear in the scene</li>
  </ul>
  
  <p>The program need to perform in real-time </p>
  
  <p>I have searched a lot but still can not find a good solution. </p>
  
  <p>Please suggest me a good method or an existing program that is suitable.</p>
