This AI turns your blurry photos into creepy HD faces

Duke researchers say the tool outperforms other photo correction methods


This AI turns your blurry photos into creepy HD faces

Even the best photographers get the occasional blurry snaps. But the mediocre ones like me get them all the damn time.

Thankfully, a new AI tool can make even crappy snappers look like Mario Testino. Okay, thatā€™s a slight exaggeration. But it does an impressive job of giving fuzzy portraits a creepy, HD makeover.

The tool was developed by Duke University researchers as a new approach toĀ photo correction. It works by searching through AI-generatedĀ images of HD faces until it finds ones that look like the input image whenĀ compressedĀ to the same size.

The photos are created using generative adversarial networks (GANs), which produce new pictures by pitting two neural networks against each other. One of them generates new images and the other checks how they look. The first network gets better with experience until the second thinks the images could pass as the real thing.

The team says it can turn a handful of pixels into realisticĀ faces with up to 64 times the resolution of the input. They claim that it can even ā€œimagineā€ new features that were imperceptible in the original, such as wrinkles, eyelashes, and stubble. They also think it could createĀ pictures for a range of other applications, from microscopy to satellite imagery.

ā€œNever have super-resolution images been created at this resolution before with this much detail,ā€ said Duke computer scientist Cynthia Rudin, who led the researchĀ team.

My HD makeover

I put Professor Rudinā€™s bold claim to the test. When I fedĀ the system a slightly pixellated picture of me, hereā€™s what it spat out:

I think the results are rather flattering. Iā€™m not mad on the Lego hair, but Iā€™d definitely consider a face swap with either of these hunks.

Letā€™s see how it did when I pixellated myself into oblivion:

Now Iā€™m genuinely impressed. The photos donā€™t quite look me, but they could pass as cousins from the uncanny valley.
