title: object tracking in real time via opencv and python
body: <p>I'm looking for good algorithm to do object tracking in real time.
  the best one I found so far was camshift but the problem with that is that I need to object detection will come from out side image.(I give the algorithm an image and he find it in the video...) and camshift required to select the ROI points with the mouse. I tried to change it but it didn't succeed.
  I'm open to learn new algorithm or to change the camshift. </p>
  
  <p>Thanks.</p>
