title: Is the "Good Features to Track" theory some way implemented in OpenCV?
body: <p>I have read in : <a href="http://faculty.cs.tamu.edu/jchai/CPSC641/shi_tomasi_94.pdf" rel="nofollow">this PDF</a> that If I want to track object I do not have to track all the images(BRUTEFORCE) in video stream. It is enough to get the object in image of the video sequence and on the other images just focus on that object, It is some way implemented in OpenCV?</p>
  
  <p>PS.: I know it is pretty old text :) Thanks</p>
