The scanner is faster because it collect less data.
The image is sharper because it have more data.
Where did the missing data came from?
It came from the training data set, not the patient.
No matter how good the image look like, it is not something from from the patient.

- tomrod 3y agoCorrect. And the extrapolation region for the MRI is reasonable, I reckon, versus extrapolation into pulling enhanced blurry photos!
- andreyvit 3y agoNot 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.
- kookamamie 3y agoFrom 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.
- jncfhnb 3y agoIf the model learns that it can get fundamentally the same information from a lower res scan then it’s moot though.
