title: Face recognition in offline videos
body: <p>I am looking for tools to recognize faces in several mp4 files. I stumbled upon the opencv library but I was hoping that somebody might have written some example code that I could check out or point me to some other tools.</p>
  
  <p>The task is as follows: I have a set of about 600 people with lots of training images. I would like to know whether these people appear in my set of several dozen mp4 videos (usually, about 50-100 appear in each video).</p>
  
  <p>Thx</p>
