title: How to show that findContours does the same thing as cvBlob does
body: <p>I have a supervisor who wants to use only cvBlob to find connected components. </p>
  
  <p>How can I prove to him that findContours can do the same? I already showed him c++ and matlab codes to prove my "theory" but he is not convinced yet. </p>
  
  <p>Is there any reference from OpenCV developer that findContours can find blobs indeed?</p>
