How was the face in the video recognized in the Nexus 7 (2013) ad?

Question

Google

Good afternoon!
I couldn’t find the information, but I’m very interested in how and with what it is possible (if it’s possible and it’s not just for beauty) to recognize faces in a video and get information about a person, as shown in the Nexus 7 (2013) advertisement video from 20 seconds:



Maybe someone knows?

Answer 1

This is a functionality in Google Play Movies. It is closed and not available for all films yet. In Russia, I have never seen it working, but in the description of the application, Google writes that it works.
