Gun Detection AI is Being Trained With Homemade 'Active Shooter' Videos (vice.com) 293

In Huntsville, Alabama, there is a room with green walls and a green ceiling. Dangling down the center is a fishing line attached to a motor mounted to the ceiling, which moves a procession of guns tied to the translucent line. From a report: The staff at Arcarithm bought each of the 10 best-selling firearm models in the U.S.: Rugers, Glocks, Sig Sauers. Pistols and long guns are dangled from the line. The motor rotates them around the room, helping a camera mounted to a mobile platform photograph them from multiple angles. "It's just like a movie set," said Arcarithm president and CEO Randy E. Riley. This process creates about 5,000 images of each gun floating ethereally. Arcarithm's computer programmers then replace the green backdrop with different environments, like fields, forests, and city streets. They add rain or snow or fog or sun. A program then randomly distorts the images. The result is 30,000 to 50,000 images of the same gun, from multiple angles, in different synthetic settings and of varying degrees of visibility.

The point of creating this vast portfolio of digital gun art is to feed an algorithm made to detect a firearm as soon as a security camera catches it being drawn by synthetically creating tens of thousands of ways each gun may appear. Arcarithm is one of several companies developing automated active shooter detection technology in the hopes of selling it to schools, hotels, entertainment venues and the owners of any location that could be the site of one of America's 15,000 annual gun murders and 29,000 gun injuries. Among the other sellers are Omnilert, a longtime vendor of safety notification software, and newcomers ZeroEyes, Defendry, and Athena Securities. Some cities employ a surveillance system of acoustic sensors to instantly detect gunshots. These companies promise to do one better and save precious minutes by alerting police or security personnel before the first shot is fired.

    I am not seeing what the big deal is. If you are going to be making an AI to detect guns, you will need give it information to help identify it. Hollywood depiction of guns and how they use, are often considered fake. Often because they need to be sure that people see the Gun, and a lot of focus on the actor and he is holding a Gun in a way that is more dramatic, vs practical.

    Homemade videos probably will work better. As it is difficult to plan and record a real high quality Active shooter shot, as it crosses many ethics violations.

    • The way guns are used in Hollywood is quite often impractical, and often quite dangerous. I remember a podcast where the host commented on the common pose people playing police officers and detectives he called "the full Sabrina". I didn't get the reference but he explained this was from the show Charlie's Angels where the camera would focus in on the face of a female character where she's holding a pistol with both hands, pointed into the air, an inch from her nose. This is exceedingly dangerous.

    Incidentally, if you're a madman intent on going on a rampage with a firearm, there's an easy fix for your problem: choose a little-known gun - or better, one that doesn't look like a gun [youtube.com].

    • It's an attempt at a stop-gap at best. So-called 'AI' is so shitty that I'll expect some kid with a finger-gun to get slammed to the floor by some security guard, if not just plain shot outright. Meanwhile the dedicated nutjob who wants to kill kids at a school will just change up to pipebombs or something, or locking all the doors and burning the place to the ground, or something else. Violent assholes will find a way to be violent assholes. The real key to all this is to detect who are the violent asshole
      • The real key to all this is to detect who are the violent assholes before they do violent things and stop them.

        I have a feeling the real key to solving the problem of violent idiots with firearms is to bring up children in a society that does not promote violence with firearms and idiocy, so that they have a chance at becoming mentally stable, educated, peaceful adults.

        Take the Swiss for example: each and every one of them has a rifle, yet you never hear stories about rogue shooters in Switzerland.

  • I can't wait to see the video where the minigun zeros in on the bad guy and safely shoots the fire arm our of his hand!

  • So in the near future, you have a gun, and the drones come and take you down. Way to go for Skynet! And all are a hack away from being maliciously used.

    "Some cities employ a surveillance system of acoustic sensors to instantly detect gunshots. These companies promise to do one better and save precious minutes by alerting police or security personnel before the first shot is fired.

    Guess I'm calling bullshit on this one rather quickly.

    We act as if the difference between life and death these days is measured in seconds by recognizing something that looks like a gun in surveillance videos that will somehow be connected to some kind of rapid-response-law-enforcement-only 911 system. Have any of you actually SEEN what "surveillance" STILL looks like in the 21st Century, or better yet, law enforcement response times? Give me a fucking break. I'm not sure who's the bigger snake oil salesman here; those selling "life-saving" gun-detecting bullshit, or those selling "HD" surveillance.

  • SmarterEveryDay did a video [youtube.com] last year where he covered some tech just like this that basically hooks straight into security cam footage. I found it pretty coincidental that Destin is also in the Huntsville area as well. Seems the company he showed off though was Lantern LLC -- completely different. The technology is the same idea though.

  • This process creates about 5,000 images of each gun floating ethereally

    Is there a big problem with disembodied firearms shooting places up?
    This is part of the problem of failing to understand the problem; guns really don't float around killing people, criminals and the mentally deranged kill people with guns (and knives, and ropes, and cars, and airplanes, etc).

  • They'll shoot up the next school with the 11th best-selling gun.

  • I thing a big sock with strategically placed holes is all that would be required to get a handgun past this kind of detection. And that's just in five seconds of thinking about it. There would be LOTS of ways to successfully camouflage handguns without compromising their usability very much. Longer guns would be more difficult, but where there's a will there's a way, and human ingenuity in such matters is pretty much limitless.

      This.

      I can see the politics of this going horribly wrong [theregister.com].

      From the description, it appears that the AI is only trained on the invisible man. In my limited experience, guns hung from the ceiling by strings are fairly inert.

  • Sorry for shooting your wife, but that our algorithm detected the corn dog she was eating as a Glock 19.

    So they are not including toy guns, nor pellet guns, nor other objects that are similar to a gun like a cell phone or sandwich.

    It is not identifying the gun that is the problem, it is identifying when something looks similar to a gun but is not a gun.

  • ... that this AI won't perform as well on California compliant guns.

  • Just train the AI system on Hi-Points. That'll cover most of the problem cases.

  • Do any of the pictures include a hand being wrapped around the gun? A book bag? A long coat? I don't often see guns waving around in mid-air.
