I need to deblur images containing strongly blurred texts.

All images look the same (i.e. the text use the same font / size / color) and I can guess part of the text inside the pictures.

I tried version 1.27 of SmartDeblur (available on GitHub) as suggested by jaclaz in this thread
https://www.forensicfocus.com/Forums/viewtopic/p=6586815/#6586815

However, in my case, the pictures look like this one and are too blurred.

The green rectangles shows where I can guess the text.
I could process dozen of other similar pictures for the machine to learn.

So I'm looking for a software where I can enter that such text is "Airport" and then would be able to detect patterns like "Air".
Probably something based on the correlation of sub-pictures. This is kind of Optical Character Recognition with machine learning.

Thank you for your suggestions.

Are the images you have the actual size of the one you posted?
444x325?

Besides blurred the font seems like only 4 or 5 (maybe 6) pixel high.

And the image looks "strange" as there is very little contrast ant the graphical parts are seemingly much less blurred than text. ?

If this is the case "guessing" is the most you can do (and I wonder, if that is the actual size of the image how you can guess anything), as there is simply too little information, see as a reference

If your "real" images are larger, post a sample.
