Berlin Artist's 'Digital Camouflage' Shirt Makes YOLO Surveillance Cameras Miss People

Artist Simon Weckert created a "digital camouflage" shirt: worn in front of a camera, the image recognition AI stops labeling the wearer as "PERSON." The trigger: Berlin police deployed the city's first police-run object recognition surveillance cameras at Kotbusser Tor, which can detect lying down, loitering, fighting, and other "anomalous behavior" that triggers police response.
How it works: Weckert ran open-source YOLO on his own camera, starting from a random pattern and using gradient ascent to iteratively tweak colors, rotations, and flips, driving down YOLO's person-detection confidence until the algorithm can't recognize the wearer. The catch: police won't disclose their algorithm, so he can only guarantee it works against YOLO — he plans to release new pattern "editions" for every new YOLO release.
He says the project is less about evasion than empowerment: showing people there are tools to push back against surveillance rather than passively accepting it.
