I&#x27;m not sure how leading edge the openbr stuff is, AFAICT (i&#x27;m not a domain expert or even novice), it&#x27;s pretty primitive. If you were starting from scratch today, i&#x27;d say the openface project (<a href="https:&#x2F;&#x2F;cmusatyalab.github.io&#x2F;openface&#x2F;" rel="nofollow">https:&#x2F;&#x2F;cmusatyalab.github.io&#x2F;openface&#x2F;</a>) is a better starting point.<p>Having a DNN that maps images of faces into a point on a hypersphere seems eminently practical. I&#x27;m a bit surprised that it works, but having something like that is awesome.
