Video Surveillance is Useless

Found this interesting slide presentation form Peter Kovesi, inventor of phase congruency edge detector. It basically saying, that on current tech level video surveillance is useless for face identification. What follow is that it’s actually harmful, due to wrong impression of it’s reliability.
Also on his page – some fun animation or How to Animate Impossible Objects
PS Fourier phase approach to feature detection looks really promising, especially if to find some low computation cost modification.

  1. dont you think in real life people use multiple “frames” to recognize other people as well as other clues, too? it is far easier to recognize other people “live” than to find them in crowd in some picture.

  2. Actually I myself always had a problem with face recognition, even face to face. It may means there is some kind of hardwired neural net in brain responsible for process, some kind of Bayesian network may be. The point is – not only computers have this problem )))

  3. sure thing, there is a medical condition causing people to lose their face recognition completely – prosopagnosia
