I would like to convert images of blurred text, like this:

enter image description here

Into a quality similar to this, with sharp edges and not "pixilated":

Background: I'm currently working on pipelines to upgrade the video qualities of recorded classes. I intend to do that frame by frame. So far, I need a command to transform this category of images (mainly with text) into better-quality ones.

My problem is, I don't know and I didn't find any specific filters that could be helpful.

  • Have a look at the Lucy-Richardson method. (For the PSF, consider using a blurred dot.) –  Nov 27 '21 at 16:15
  • Can you post (part of) the image at full size? It is also possible that this is already doable in a video editor (likely a blend of contrast and sharpening). – xenoid Nov 28 '21 at 09:41
