Scientists dupe infrared cameras with thermal camouflage

Scientists have created a graphene-based material that can outwit thermal cameras by masking hot objects. The film provides a layer of camouflage by appearing to match the ambient temperature, potentially making the object it's covering seem invisibl...

German railways hope to fight graffiti with thermal imaging drones

DNP German railway operators consider drones to nab graffiti artists

Drones aren't just for war, creating airborne logos or patrolling Aussie beaches. If German railway operators have their way, they'd be used to capture graffiti artists, too. Motivated by the high cost of property damage incurred by spray-painting vandals (around 7.6 million euros / $10 million a year), the Deutsche Bahn will soon begin testing miniature helicopter-style drones in the hopes of identifying those responsible. Each remote-controlled chopper is equipped with an infrared sensor capable of thermal imaging and producing high-resolution photos that would be useful to authorities. The tiny aircraft can also fly up to 150 meters (500 feet) and as fast as 33 mph and would cost about 60,000 euros ($77,550) each. The Bahn assured the public that the mini drones will be restricted to highly targeted areas, which should help allay those privacy concerns.

DARPA flaunts HD heat vision camera small enough to carry into battle

DARPA thermal camera

Thermal imaging cameras are highly useful tools for military and law enforcement types, letting them see humans inside buildings or land a helicopter in the fog. High-definition models are too heavy for servicemen to tote, however, so DARPA and a private partner have built a 1,280 x 720 LIWR (long-wave infrared) imager with pixels a mere five microns in diameter. That's smaller than infrared light's wavelength, allowing for a slighter device without giving up any resolution or sensitivity while costing much less, to boot. Researchers say that three functional prototypes have performed as well as much larger models, allowing them to see through a simulated dust storm, among other tests. If DARPA ever lets such goodies fall into civvy hands, count us in -- you can never have too much security.

Scientists develop pair of algorithms that could enable thermal cameras to pick out drunk people

Scientists develop pair of algorithms that could enable thermal cameras to pick out drunk people

We're not sure if Georgia Koukiou and Vassilis Anastassopoulos of the University of Patras in Greece like a tipple or not, but the pair have developed two algorithms that, when used with thermal imaging, could pick out drunk people in crowds. What is it that betrays your best intentions to look sober? As always, your face. Booze causes the blood-vessels in your visage to dilate, and the researchers used this principle to compare facial scans against a database of tipple-free mug shots. Likewise the duo found that when under the influence, the nose gets warmer, while the forehead cools -- another visual check that the infrared can help identify. The hope is that using this technology, law-enforcement can make a judgement call based on more than just your wonky walk. But in our experience, the troublemakers are pretty good at outing themselves.
