The MRI scanner near you is potentially using AI to increase image signal, then to increase pixel count 4x (well, 2x in X direction, 2x in Y direction. Potentially also generating a slice between each slice in 3D datasets).
If you turn off the AI and actually acquire the information, the scan is long, the patient moves and it is blurry. However if the patient is still, the non AI images look like the AI images.
Disagreeing with it is sort of moot now - it’s in the machines and is running. It works well, I’ve been using it daily for a few years.
All vendors have it - I use the Siemens product ‘Deep Resolve’ [1]. Their PR department undersells it, in my view this is a bigger change than the 1.5T to 3T transition.
Which may well be, but those detectives still aren't going to suddenly be able to read the license plate from an "enhanced" blurry photo, like their TV counterparts were doing back in the early 00s.
Not necessarily. As long as some mashed pixels of the license plate remain, and assuming different license plates would result in differently mashed pixels, it might be possible to restore the original from the highly compressed image data.
From series of images, aka. video, sure. From a single image? Not so much.
In video there is a lot of temporal information and even if the spatial resolution wasn't high enough in a single image, one would be able to accumulate a higher resolution version of the scene using multiple observations.
