Recent articles about supers, prosopagnosia, policing and face recognition research

I was glad to read in this substantial and interesting article that face identification was not the only evidence used to convict criminals. And the last couple of sentences in this piece are too true!

Not one but four recently published studies of super-recognition!!!!

And all bar one are open access! Please readers let me know if there are more studies on supers out there.

The above paper interesting as it apparently supports the idea that developmental prosopagnosia is a heterogeneous condition and at least the most severe cases are not simply the bottom end of a spectrum of ability. The authors do seem to regard supers as the top end of a spectrum though. Researchers also found that supers and able controls spent more time looking at noses, a finding which I think I recall from another study. It makes sense to me as I feel that great face recognition ability is an automatic and involuntary process (like synaesthesia) that involves perception of the face as a whole “landscape”.

Wow, I just lost all respect for The Met

…which is a pity as the Metropolitan Police in London are apparently world leaders in the use of super-recognizers in law enforcement.

Recent online articles about super recognizers, and a link to a test

Madhumita Venkataramanan’s article for the BBC (third down) is well worth your reading time. I wonder whether Madhumita might have read my tips for acing or gunning tests of face memory?

Doco about the UK 2011 riots on Australian television tonight

At 9.30pm on ABC2 (channel 22) an episode in the series Our Crime titled Riot is scheduled for broadcast. It is about the 2011 riots in England, and the CCTV and personal mobile phone footage of the crimes. I don’t know if the role played by police super-recognizers in investigating these crimes will be covered on this TV program, but I guess it might.

http://www.abc.net.au/tv/programs/our-crime/#episode/ZX9697A001S00

I have now watched the program I didn’t notice any discussion of face recognition or supers, but the episode was well worth watching to gain some insight into the way different people think and behave, but mostly to get to know about the amazing Pauline of Hackney. What a star!

They are developing tests for recruiting super-recognizers into the police in the UK, but don’t ask me what’s happening here

Phillips, Mark London police using crime-fighting “super recognizers” official. CBS News, Dailymotion. Publications date November 12th 2013. http://www.dailymotion.com/video/x173o5e_london-police-using-crime-fighting-super-recognizers_news

This is an American report from CBS News published in November 2013 on the use of super-recognizers in London policing. Detective Chief Inspector Mick Neville explains how inadequate computer facial recognition was found to be compared with results from police supers. PC Gary Collins and researcher Dr Josh Davis are also interviewed, and super-recognizer police doing identification work are shown. It is revealed that tests are being developed for recruiting super-recognizers into a police force in London. My guess is that this would mean recruiting supers into the police force because they are supers, in addition to their existing policy of finding and utilizing the many supers that they already have serving in this large police force.

“The Met” continue to be leaders in the use of human facial super-recognition in policing, but what is happening here in Western Australia with regard to human face recognition and CCTV and policing? As far as I can tell, not a lot. As far as I know there is no testing of any kind of face recognition or face memory ability in police recruitment, and I’ve not read anything about use of supers in any Australian police force. In September 2013 the Weekend West had an article in it about operators at the City of Perth’s surveillance centre working with and beside members of the WA Police to keep things under control in the city streets. The journalist wrote about the tens of millions of dollars that the City of Perth has spent on their CCTV camera network, the “unique” skill set of the surveillance centre operators, their intuitive understanding of body language, their eye for detail, multitasking ability, the keen competition for their jobs and some rigorous battery of testing in which only one out of 160 applicants met the required standard, but not a single mention of face recognition or visual memory.

A webpage of a software company ABM boasts that it provides the WA Police with facial recognition technology for use on photos and other static images of offenders, which will probably impress the “boys who love toys” technophile set, but it fails to impress me for a couple of reasons. Firstly, there appears to be good evidence that the most able humans can vastly out-perform contemporary facial recognition technology, and secondly, the identification of people from still images of faces or entire bodies is inherently limited. It does not use the wealth of information that one can glean from looking at a moving image. Faces are unique and so are the ways that people move. A moving image is essentially richer and more complete and more natural than looking at a single still image. Study of interviews of super-recognizers yields many clues that supers recognize people, not images and not just faces. Supers can identify people from photos, but it seems likely that the memorization process works best if it is based on watching people, not looking at photos. I am not aware of any face recognition technology that works off moving images, but that might just be a mark of my ignorance. I remain skeptical.

The idea that technology must beat humans in face recognition is a popular one, I think based on some major misconceptions about human psychology and artificial intelligence. I think a lot of people assume that if tasks like visual identification or walking or recognizing voices are effortless for humans then they must be even more easy for a computer system to perform. This shows an ignorance of the millions of years of biological evolution that gave humans and even the most humble animals sensory perception, and the sensory and movement systems of muscles and nerves that give rise to the power of voluntary movement. These processes involve brains as much as they involve sensory organs and muscles. The fact that we are able to do these things without thinking much about them is no indication at all that they are simple. It is just an indication that some of the really clever tasks in cognition are too complex and important to be exposed to the interference of conscious thinking. Attempting to recapitulate the kind of design complexity that is found in biological sensory perception and biological movement with technology and computers would surely keep a designer occupied for a very long time. Good luck with that.
