Machine learning systems are very capable, but they aren’t exactly smart. They lack common sense. Taking advantage of that fact, researchers have created a wonderful attack on image recognition systems that uses specially printed stickers that are so interesting to the AI that it completely fails to see anything else. Why do I get the feeling these may soon be popular accessories?
I would put money on these becoming t-shirts in the near future. At the same time, I doubt they’ll do much to distract facial recognition systems. These are very domain specific and capable of tracking multiple objects simultaneously.
This method could probably be used to create fake “guns”, though, and I can see that causing some serious issues.
You can find the original paper here, which (no lie) includes an appropriately sized cut out and keep patch.
