And since video is just a barrage of images played very quickly, for an A.I. to identify things and understand them in any video, let along Live Video, is a huge feat. Candela's dream is far from reality, based on current systems that are being deployed, but his team is making headway. During his presentation at F8's keynote today, Candela announced that Facebook is working on processing video for facial recognition. With this technology, the A.I. is able to tell when someone is in a video, what time they enter, and for how long. The technology is based on the A.I.-based automatic tagging feature that Facebook has used with great accuracy for years.
