title: Retrieve gaze coordinate on screen
body: <p>I am implementing an eye tracker using emgucv (openCV C# wrapper), So far i was able to detect iris center and eye corner accurately.</p>
  
  <p>As the next step i want to get the screen coordinate where user is focusing (also known as gaze point),As a beginner to image processing , i am completely unaware of gaze mapping and gaze estimation.</p>
  
  <p>I would be thankful , if you provide any code snippets or algoritms to perform gaze mapping to retrieve gaze coordinate on screen .</p>
  
  <p>Thanks in advance</p>
