Impressive examples. Thanks for posting them! So the ridiculous „Enhance!“ one sees in TV show crime dramas could one day actually become true.

  You can't make data that isn't there. It's fundamentally going to be a guess. You can enhance your way to a face or a license plate but there is zero guarantee it will be the face or the license plate that the low quality image/video is of. This is why solid blocks of color or emojis are so effective at censoring images, it takes the data and replaces it with pure junk.

    If you know it's a gaussian blur with a known radius, you can uniquely reverse it.

      You do, however, lose colour depth information (e.g. deep color to true colour, true colour to high colour / 256 colours). Still enough to detect a face.
