title: What method does Microsoft Face API use for face comparison?
body: <p>I've been working on a facial detection and recognition program for a few days now in OpenCV using Eigen/Fisher/LBPH FaceRecognizers that will compare the faces in two photos using the 3 listed recognizers and return a confidence value that the faces are the same person or not.</p>
  
  <p>While I've been able to get everything working, the results and recognition rates have not been inspiring, especially when you look at a service like Microsoft Face API (which I cannot use due to privacy concerns) at this url: <a href="https://azure.microsoft.com/en-ca/services/cognitive-services/face/" rel="nofollow noreferrer">https://azure.microsoft.com/en-ca/services/cognitive-services/face/</a></p>
  
  <p>Does anyone here have any idea what method(s) Microsoft is using in their Face verification on the above URL? It's <em>exactly</em> what I need (my tests have shown it to be extremely accurate for my scenario), aside from the fact that it's an API and not an SDK.</p>
