Facebook researchers are looking at technology that can identify people in photos almost as precisely as humans.
Facial-recognition software already lets Facebook users suggest tags on photos.
But this new technology, called "DeepFace," is more accurate because it can identify people from the side.
Researchers say it recognizes the correct face 97-percent of the time.
A Facebook spokeswoman says it's not clear how or even if Facebook will ever use "DeepFace."
Right now, it's in the research phase.
