Can I use Firebase ML Kit (Face Recognition) to scan pictures for faces and determine if faces are found, log a user into an account? What I mean is verify that a face is found on the picture and sign a user up. Anyone?

Firebase ML Kit can perform face detection. It does however not perform face recognition.

In other words: it can tell you that there is a face in a picture (and where it is), but it can't tell you who it is.

This makes it impossible to use ML Kit for authenticating a user.

  • Okay that was very helpful. That was the exact answer I wanted. I tried this and it worked. I just want to detect faces in pictures users will upload and then sign them in. It is prerequisite for signing up. You have to upload a portrait of yourself. And ML Kit did an amazing job with just a few lines of code. Thanks again @Frank van Puffelen – Gabriel Hagan Aug 05 '18 at 23:32
  • Okay @Frank van Puffelen Definitely! – Gabriel Hagan Aug 07 '18 at 10:30
