title: Can I use openCV to compare two faces on two different images?
body: <p>I am very new in openCV, I saw it could figure out the face and return a rectangle to indicate the face. I am wondering whether there is anyway for openCV to access two images, with which contains one face, and I expect openCV to return the possibility of whether those two people are the same. </p>
  
  <p>Thanks.</p>
