back to article Ohio prof develops CCTV people-tracker 'ware

Boffins in Ohio have taken another step towards the global surveillance panopticon of the future, developing software which can autonomously track an individual through a city using CCTV cameras. James W Davis, associate prof at the Ohio State computer science and engineering department, developed the new spyware with the aid of …

Poor show, El Reg

This kind of research has been going on for years. You are reporting, I think, on the work presented in a 7-page paper from three and a half months ago ("A Fast Linear Registration Framework for Multi-Camera GIS Coordination")

http://www.cpl.uh.edu/html/LocalUser/avss2008/programarea_files/day3.html

I would guess that this is a small advance, like most research - not the solving of Computer Vision that you like to report breathlessly every few months. You would do better to try to understand the limitations of these systems and take comfort from how ropey they are.

Face recognition: Get real!

Before there is decent face recognition software, there will be a usable decompiler. The abstract mathematics underlying the two fields of endeavour is pretty much the same, but a decompiler is more wanted.

This sounds like an extension of a project i did in University, which was just moving a single camera around to track a person recognised in frame.

If it was being developed in Manchester i'd be very suspicious of my tutor.

What happens when more than one suspect (law abiding citizen) that are being tracked pass through the area covered by one camera, which suspect gets given priority?

Nice trick

You don't have to actually recognize an object in order to track it across a grid. Clever.

Having said that, somebody stop these people! Follow anybody long enough and you'll see something "unsavory" to question them about...

Oh that is cool!

Of course I'm all in favour of the tracking of some nefarious blackhat heading out of London on a motorway at 70mph with a kidnapped child victim or the contents of safe-deposit boxes or a lot of explosive. I’d definitely want her caught before anything worse happens.

What I don’t like in any of these anti-habeas-corpus/database/camera/ID systems is the thought that a future government—perhaps even while I’m still alive—will decide to intern a group of ordinary people who had never done anything bad so had always had nothing to fear until a fashion dictated that ‘terrorist sympathisers’ need to be collected up. Are you over 30 years of age, or blond+blue-eyed, or Seventh-Day Adventist? Or ‘Arabic’ whatever that may mean?

In my life and my history books I’ve seen or heard of it happening in Britain to Germans (or even those with vaguely Mittel-Europa names), in the Americas and Australia to aboriginal inhabitants, also in America to Japanese people, and to Russian-sounding ones. And to Jews in Germany (and most other places), to Christians in Italy, to Saxons in England. The list can be extended. Oh what Stalin, Napoleon, McCarthy and Hitler could have done with this system!

Can’t stop the technology, so we need checks and balances. Watch the 1980 series of Yes Minister when they argued this out. They didn’t even have to guess what nefarious behaviour was.

Nefarious!

So the next step is to catch people engaging in "Nefarious" behaviour. Lovely. A subjective term if ever there was one. What's the next step - tasers duct-taped to the cameras to automatically prevent said nefariousness from nefariating the non-nefarious?

Well, at least there is some hope. I'm sure the software won't distinguish between car theft and car clamping, so some poetic justice would be meted out...

0 day exploit

"That's the advantage of linking all the cameras together in one system - you could follow a person's trajectory seamlessly,"

so if I move around the street like smoke particles in brownian motion, I should be able to avoid being tracked when I move out of view from the first camera - assuming of course I change my direction whilst I pass from one view to another.

However not content with this, the uber geeks are also developing software to see if someone is acting out of order from the rest of his/her environment. that has 2 implications:

1 - the brownian motion exploit example will soon be rendered use less

2 - you now have to conform to being like zombies in invasion of the body snatchers.

random thoughts

In no particular order:

1. Isn't this what cellphone companies have been doing since the invention of the cellphone ? Tracking a phone as it moves from one cell to another ?

2. This depends upon a government bureacracy where the right and left hands know what each other are doing and all systems are joined up. Evidence of this capability is notable by its absence. This kind of thing could be useful for local policing of football hooligans but I think national level surveillance will continue to be labour intensive requiring a significant team to monitor one individual effectively.

3. I think automated facial recognition is quite easily defeated. Ask any hoody, or beardy, or someone with sunglasses, a hat or a scarf. The best trained police officers in the Met anti terrorism branch mistook an innocent Brazilian electrician for a suicide bomber with fatal consequences. Imagine the match had been done by machine and politicians and managers trying to get away with that one.

How to succeed at oppression without really trying...

"..write code which can pick out people "engaging in nefarious behaviour"..."

There are two ways to address this issue. You can either write complex intelligent software that can actually determine if a person is suspicious (difficult, probably impossible), or (and this is the good part) you can rewrite the laws to fit in with the technology we have at this moment in time.

Rather like 'glorifying terrorism', which is now 'illegal' and means 'liking Al-Quaeda, or not liking the Home Office', or 'extreme sex' which is also illegal and means 'anything the vice squad havn't been invited to'. We will soon have 'acting in a manner intended to spook a pic microprocessor'

I doubt that it will work if the "target" mixes in with a large crowd doing lots of moves - most cctv doesn't have the resolution not frame rate necessary to keep up.

CCTV Fail

Most digital CCTV systems nowadays use a compression system for storing the video (even for realtime viewing, the image is generally compressed, saved and then sent over the network to the operator). This means that the "live" image is of quite poor quality. Couple that with low quality lenses and wide field of vision (i.e. covering a large amount of area) etc, and you get a difficult area to work in as far as automated tracking goes.

Now, before you all think that I'm talking through my arse, I work in the Surveillance Department one of the largest Casino's in Europe, & have done for many years. I've been jointly responsible for implementing the digital system in our casino, so I do know what a difficult task the blob-tracking programmers have.

In our casino, we have as close to a perfect environment as we can - lighting controlled, access to premises controlled, almost ideal placement of cameras, etc. However, we still find it incredibly difficult to track a player from one area to another - MPEG artefacts, large crowds of people in the shot, etc. (Imagine, if you will, a field of heads and hairdo's, as everybody's too close together for you to identify clothing, and you'll begin to get an idea of how hard it is to track a badly focused blob across a crowded room with artefacting).

At least two things need to be done to make this a 'success': 1 - Higher resolution digital imaging and recording. 2 - Systems which need to be able to re-acquire a 'blob' having lost it, either by checking adjacent cameras to the last one the 'blob' was seen in, or predicting likely paths from previous data. Because, trust me on this, they will lose the person being tracked.

Btw. Easy way to fox this sort of system - electro-chromatic or themo-chromatic clothing (or a nice, double-sided jacket, to be swapped in a darkened, camera-free room).

Not That New

This technology is not that new, has already been developed by a company in runcorn 360 vision. I work for CCTV installation company and we trialled the system. I am guessing this system is the same, basically relies on absolute positioning.

The inherent problem with these systems is that when the scene changes the cameras has to re-scan the surroundings. In external situations the problem is made worse by the fact that wind causes camera shake and zoomed in images are constantly changing.

As for spotting unusual behaviour, these system are very hit and miss to say the least they only work in situations where there is a large amount of repeat or constant information, train stations, airports etc..

Spotting unusual behaviour relies on a break from the norm, which could be anything, suffice to say these systems pick up so many potential threats and behavioural patterns.

The vast majority of systems out there work best with operators.

Not surprised about this revelation.

I am surprised that none of 'em has considered the TCO of such a system. Not to mention the practicality of monitoring it, or capability of the system's Stake Holders in agreeing on the project's scope or it's capacity. Let's face it Air Traffic, NHS, National Database, what have they in common so far ?

Multiple cameras

For those who claim they'd be able to thwart the cameras by switching in the gap between one camera's view and the next, this does not account for the possibility (which I believe is stated in the article) of the cameras having overlapping fields of vision. IOW, before you step out of one camera's eye, you're already in the next one's--seamless coverage, IOW.

That's if you accept that the police made a mistake. There is a great deal of evil being done deliberatly and passed off as a mistake. It's more likely they had the right target just that they mishandled the assasination. Or was it even misshandled? They seem to have things pretty much sewn up so there are no serious conequences for their 'blunders'.

Oh we seem to have let the terrorists blow up the trains.

Oh we seem to have no CCTV footage, just a still picture that looks like it was done in photoshop by an idiot. We must tighten the regulations on hiring idiots.

Oh we seem to have shot the wrong terrorist.

Oh we can't allow the police to be charged criminally since they already said it was a mistake.

Meanwhile:

Oh we seem to have left those disks on the train.

Oh we seem to have broken the economy.

Oh we seem to have given the banks too much money which they are forced to pay out in million pound bonuses to top staff. What bad luck.

You see, I don't buy the excuse of it all being a series of unfortunate accidents by highly paid, highly qualified people in top positions of power who cannot be brought to book.

the most important part

Is that most of the footage on CCTV is of amazingly low quality (think "worse than youtube")

That's why I always find it funny on CSI or similar programs on the telly when they "magically" enhance a 100 pixel face from a block away and come up with a detail "image" of the person they're after.....ha.ha.ha......not bloody likely!
