title: Car detection with openCV using android
body: <p>I'm developing an application that detects and counts the cars. </p>
  
  <p>my problem: I can not recognize the car, I can count them but if for example a person has passed her too. </p>
  
  <p>How do I recognize the car? 
  Also, if it passes a bus or large middle has more than one, how can I solve this?
  I hope I was clear
