  <p>the features is part of a video. As the video is played, the feature keeps moving around but never goes out of the rectangle of size shown in figure.</p>
  
  <p>I wish to track the center point over the duration of the video.</p>
  
  <p>*the red point is not part of the image. I have overlaid it to show the center point I wish to track.</p>
