title: Detect face then autocrop pictures
body: <p>I am trying to find an app that can detect faces in my pictures, make the detected face centered and crop 720 x 720 pixels of the picture. It is rather very time consuming &amp; meticulous to edit around hundreds of pictures I plan to do that.</p>
  
  <p>I have tried doing this using <a href="http://creatingwithcode.com/howto/face-detection-in-static-images-with-python/">python opencv mentioned here</a> but I think it is outdated. I've also tried <a href="http://www.givp.org/blog/2011/06/13/image-cropping-and-face-detection/">using this</a> but it's also giving me an error in my system. Also tried using face detection plugin for GIMP but it is designed for GIMP 2.6 but I am using 2.8 on a regular basis. I also tried doing what was posted at ultrahigh blog but it is very outdated (since I'm using a Precise derivative of Ubuntu, while the blogpost was made way back when it was still Hardy). Also tried using Phatch but there is no face detection so some cropped pictures have their face cut right off.</p>
  
  <p>I have tried all of the above and wasted half a day trying to make any of the above do what I needed to do.</p>
  
  <p>Do you guys have suggestion to achieve a goal to around 800 pictures I have.</p>
  
  <p>My operating system is Linux Mint 13 MATE.</p>
