I'm curious about this photo-enhancement tool, because it's also a common joke in some circles that police procedural TV shows use "Zoom! Enhance!" when blurry photos -- or photos zoomed in until they're pixelated -- typically can't be enhanced for information-theoretic reasons. (Of course, if you can make assumptions about what the photo is of and what structure that thing would have, you can make relatively-likelihood estimates of different possibilities for the subject matter, such as different text strings in a blurry or pixelated photo of text.) So, under some assumptions this typically shouldn't be able to work. :-) edit: extensively documented at https://tvtropes.org/pmwiki/pmwiki.php/Main/EnhanceButton https://tvtropes.org/pmwiki/pmwiki.php/Main/EnhanceButton, for example
