Collaborate Disseminate
While we’ve already seen materials that allow people or objects to hide from heat-detecting cameras, they’re typically only effective at one ambient temperature. An experimental new material, however, can be user-adjusted to work over a wide range.Cont… Continue reading Heat-camo material can be adjusted to match ambient temperature
From the New York Times: Now, a paper published last week in Nature Communications suggests that their chromatophores, previously thought to be mainly pockets of pigment embedded in their skin, are also equipped with tiny reflectors made of proteins. These reflectors aid the squid to produce such a wide array of colors, including iridescent greens and blues, within a second… Continue reading Friday Squid Blogging: New Research on Squid Camouflage
They have advantages: Pigeons are certainly no substitute for drones, but they provide a low-visibility option to relay information. Considering the storage capacity of microSD memory cards, a pigeon’s organic characteristics provide front line forces a relatively clandestine mean to transport gigabytes of video, voice, or still imagery and documentation over considerable distance with zero electromagnetic emissions or obvious detectability… Continue reading Military Carrier Pigeons in the Era of Electronic Warfare
Both the US Drug Enforcement Administration (DEA) and Immigration and Customs Enforcement (ICE) are hiding surveillance cameras in streetlights. According to government procurement data, the DEA has paid a Houston, Texas company called Cowboy Streetlight Concealments LLC roughly $22,000 since June 2018 for "video recording and reproducing equipment." ICE paid out about $28,000 to Cowboy Streetlight Concealments over the same… Continue reading Hidden Cameras in Streetlights
According to new research, the fuzz you see on the chest of moths is specifically designed to muffle sound and protect them from bats. Continue reading Deaf Moths Use “Acoustic Camouflage” to Evade Echolocation
What is suspicious about the books in the image above? Is it that there is no bookend? How about the radio waves pouring out of them? [Clay Weiland] does not like the way a bare router looks in the living room, but he appreciates the coverage gained by putting it in the middle of his house. He added a layer of home decorating camouflage in the form of some second-hand book covers to hide the unsightly bit of tech.
There isn’t a blog post or video about this particular build anywhere. The photos were submitted to our tip line as-is …read more
The good people at MIT’s Computer Science and Artificial Intelligence Laboratory [CSAIL] have found a way of tricking Google’s InceptionV3 image classifier into seeing a rifle where there actually is a turtle. This is achieved by presenting the classifier with what is called ‘adversary examples’.
Adversary examples are a proven concept for 2D stills. In 2014 [Goodfellow], [Shlens] and [Szegedy] added imperceptible noise to the image of a panda that from then on was classified as gibbon. This method relies on the image being undisturbed and can be overcome by zooming, blurring or rotating the image.
The applicability for real …read more
