Thanks for your comment. This makes sense - I would use Watson to determine which photos have humans at all, and then run those through, e.g., my facial recognition software. But Watson would keep me from having to waste resources looking for faces in photos of trees, for example.

I'm not in this field, so I'm having trouble understanding what use cases / consumer facing features this API unlocks. Your comment is very helpful in that regard.
