title: Algorithms for finding a look alike face?
body: <p>I'm doing a personal project of trying to find a person's look-alike given a database of photographs of other people all taken in a consistent manner - people looking directly into the camera, neutral expression and no tilt to the head (think passport photo). </p>
  
  <p>I have a system for placing markers for 2d coordinates on the faces and I was wondering if there are any known approaches for finding a look alike of that face given this approach?</p>
  
  <p>I found the following facial recognition algorithms:

  <p>But none deal with the specific task of finding a look-alike.</p>
  
  <p>Thanks for your time.</p>
