Get the picture? Pixelisation

Blurring images promotes prudery, as in tabloid reports of wardrobe malfunctions, and privacy：in Google’s Street View pictures perhaps even that of your own image. Now Google Brain, an offshoot of the Silicon Valley behemoth working on a form of artificial intelligence called deep learning, is finding ways around it. That is tricky: the original picture’s information has been lost, smeared out both visually and mathematically. Google’s work combines two “neural networks”, a computational approach that mimics the brain’s neurons, to guess what’s gone.
