Designed to attack detectors rather than classifiers, these wearable “universal patches” delete you right out of a machine’s vision.

A team of researchers at University of Maryland, College Park, working with Facebook AI, have developed a real-life “invisibility cloak:” a sweater that renders you a ghost to common person-detection machine learning models.
“This paper studies the art and science of creating adversarial attacks on object detectors,” the team explains of its work. “Most work on real-world adversarial attacks has focused on classifiers, which assign a holistic label to an entire image, rather than detectors which localize objects within an image. Detectors work by considering thousands of ‘priors’ (potential bounding boxes) within the image with different locations, sizes, and aspect ratios. To fool an object detector, an adversarial example must fool every prior in the image, which is much more difficult than…
