Terrifying really

Well.......shit.

Frigging frigg

Object detection was great at fooling Recaptcha until they started using adversarial images. That's the real reason they're grainy and blurry and noisy--reallly fucks up convolutional networks

Actually that captcha method serves exactly the above purpose if you think about it.
Through letting people choose the street signs the machine learning model gets trained so the self-driving cars will recognise those better.
