I speak as someone who invented and produced both face-recognition and
video-motion detection systems (two commercial systems, and who knows
how many prototypes) for more than 8 years, and these systems can, as
Ziya says, *easily* produce metadata by the bucketloads; colors,
shapes, items, gestures, movement, environment, places ... the list
goes on. These systems have exsisted for years, but it hasn't been
until recently they've entered the more common fields of computer
software.My first system, who could tag any time-lapse of video with
basic metadata such as environmental states (rain, fog, steam, night,
day, season) and people states (how many in the pictures, which way
they're going, and basic colors of what they're wearing) we started
selling to prisons and other high-security places back in 1990. I
assume *lots* have happened since I left the industry in 1997.

These things aren't fantasy, only a bit hidden from the normal person.
