One of the really cool things from the pdf is the ability to construct a normalized face from a video frame: https://i.imgur.com/SdRHCJ0.png https://i.imgur.com/SdRHCJ0.png Basically they are taking a video frame, making it face forward, cancelling out lighting for pure albedo, and removing accessories like glasses. This is incredible in terms of tracking individuals. It's a digital mugshot. Also, I think it's interesting that the classifiers can pick out ethnicity with a high degree of accuracy. Seems like an easy way to fool this tech, from a privacy perspective, is to talk stereotypically like a specific ethnicity.
