title: OpenCV Kalman Filter python
body: <p>Can anyone provide me a sample code or some sort of example of Kalman filter implementation in python 2.7 and openCV 2.4.13 </p>
  
  <p>I want to implement it in a video to track a person but, I don't have any reference to learn and I couldn't find any python examples.</p>
  
  <p>I know Kalman Filter exists in openCV as cv2.KalmanFilter but I have no idea how to use it. Any guidance would be appreciated </p>
