title: Count the number of people in the video
body: <p>I am working on image processing and computer vision project.  The project is to count the number of people entering the conference.  This need to done in OpenCV or Python.</p>
  
  <p>I have already tried the Haar Cascade that is available in OpenCV for Upper body: <a href="https://stackoverflow.com/questions/31834415/detect-upper-body-portion-using-opencv">Detect upper body portion using OpenCV</a></p>
  
  <p>However, it does not address the requirement.  The link of the videos is as follows:</p>

  <p>If you view the sample1 file, at 0:16 secs a person is entering the room, that would always be the way.  The camera is on top of the door.</p>
