title: Tracking blobs with OpenCV
body: <p><br>
  I have an EMGU (openCV wrapper) program that subtracts the background from<br>
  a camera feed and extracts nice clean blobs.<br>
  Now I need something that will track these blobs and assign them with IDs.<br>
  Any suggestions/libraries ?<br>
  <br><br>
  Thanks,<br>
