Author: Brian Karas, Published on Feb 10, 2017

"Zoom in and enhance, I think there is a clear shot of his face in the reflection" has been the kind of statement CCTV users have wanted to make reality for years.

Hollywood has imagined this technology, but now engineers at Google have released a whitepaper on "Pixel Recursive Super Resolution", showing real-world examples of upsampling a highly pixelated image into one with details and recognizable features.

In this report we examine Google's super resolution whitepaper, and how this technology could impact the security industry.
