In the last few years computers have made massive advances in image recognition. Neural networks especially — systems which can be trained over time — have become eerily good at describing even quite complex scenes. However, as this video from US artist and coder Kyle McDonald shows, they’re far from 100 percent accurate. McDonald modified a neural network built by researchers from Stanford and Google to analyze footage from a live webcam feed on his laptop. He then went for a walk around Amsterdam and let the computer do the talking.
