There was a video many years ago (early 2010s?) demoing a similar technology, which would overlay and blend many images on top of each other to make a fuzzy image approximating what was actually being viewed.

Edit: found it! https://youtu.be/nsjDnYxJ0bo

The youtube video quotes a paper by the same author, so it's probably the same group's work. I wonder why didn't they used an approach similar to the one in the video using SD - it looks more viable.

Because it's from 11 years ago when SD wasn't around.
