AI giving super resolution to images

Most ZDNet readers know enough about digital photography - and video - to know that enlarging a digital picture means the pixels get bigger too. Blowing up a fuzzy surveillance video just makes a large fuzzy video. It's why optical zoom is superior to digital zoom in a camera. However, there is a lot of work going on in the field of image super resolution (ISR), and they've produced some amazing results. The problem is, of course, that you don't know what the image under those pixels looks like.
