"Enhance" is real. When will this stuff trickle into lower level law enforcement?
EDIT: Furthermore the range of plausible imaginary images that match a given input is high (infinite?).
This paper does not demonstrate an enhancement technique but a phenomena which those using inverse methods called "overfitting".
(Because these kind of techniques aren't really enhancing the images in a way that gives you new and useful information: they are taking the low-res images as input, and giving you a plausible high-res image as output, based on it's training data. It is NOT however trying to say "this is the ACTUAL high res image that generated this low-res image"
