title: Facial expression recognition from webcam
body: <p>I am currently working on a project where I have to extract the facial expression of a user (only one user at a time from a webcam) like sad or happy.</p>
  
  <p>There are a lot of programs/APIs to do face detection but I did not find any one to do automatic expression recognition.</p>
  
  <p>The best possibility I found so far:</p>
  
  <p>I used OpenCV for face detection earlier, which was working great, so If anyone has some tips on how to do it with OpenCV, that would be great!</p>
  
  <p>Some user on a OpenCV board suggested looking for AAM (active apereance models) and ASM (active shape models), but all I found were papers.</p>
  
  <p>-So i'm Using Active Shape Models with <a href="http://www.milbo.users.sonic.net/stasm/">Stasm</a>, which will give me access to 77 different points within the face, so I would still have to manually map them to expressions.</p>
  
  <p>Any programming language is welcome.</p>
