Tiny, blurry pictures find the limits of computer image recognition

Computers have started to get really good at visual recognition. They can sometimes rival humans at recognizing the objects in a series of images. But does the similar end result mean that computers are mimicking the human visual system? Answering that question would indicate if there are still some areas where computer systems can't keep up with humans. So, a new PNAS paper takes a look at just how different computer and human visual systems are.
