title: OpenCV Human Body Tracking
body: <p>Hi I am new to OpenCV and I am trying to implement human body tracking using a camera placed on a fixed position. I did a bit of a research and I came across Histogram of Oriented Gradients method but based on my understanding what it does is detection instead of tracking. Therefore I was wondering what is the simplest way to implement human detection and tracking on OpenCV? </p>
  
  <p>P/S: I found this <a href="http://www.youtube.com/watch?v=5uCbEvXL94Q" rel="nofollow">video</a> and it is precisely what I wanted to achieve.</p>
