Background removal and cleanup of book scan

I did so.
I will do again 20 times.

What does that mean?

From 20 attempts i get 5 x time out error.

Yesterday I had a few times the same error. This doesn’t help you, but now you know that you are not doing anything wrong. Maybe this has something to do with the G’MIC server?

Try installing the latest prerelease of G’MIC.

https://gmic.eu/files/prerelease/

After installing this prerelease, hit the refresh button.

Now i downloaded the prerelease-file. In the About → Download External Data there is the information that i have to copy the decompressed files to
user\appdata\GMIC.

I found the directory
…\appdata\Roaming\GMIC
May i kindly ask if this is the correct directory for to get the prerelease working as a plugin in GIMP?
Well, the content of the directory (left side) is quite different than the content of the decompressed Zip-File (right side).
Sorry for this Newbee-Question.
Thank you very much!

That doesn’t look right. Download:

https://gmic.eu/files/prerelease/gmic_gimp2.10_qt_win64.exe or
https://gmic.eu/files/prerelease/gmic_gimp2.10_qt_win64.zip


PS
– I downloaded the *.zip file.
– Searched for all of the gmic*.exe files and found the folder with the plugin version.
– Backed up those files.
– Extracted the zip into the folder.
– Renamed gmic_gimp_qt.exe to whatever the original file was called (mine was gmic-qt.exe).
– Restart GIMP if it is open.

I followed your instruction with success. Juhu - and the result is incredible!!
Best scan processing ever!!
I worked out that with 0,44 - 90 - 90 the image is softened and very good. But
0,33 - 96 - 97 i get the best results. WEith 0,34 - 96 - 97 it is smoother. If i change the second slider just to 97 the whole page is black. The filter works wonderful.

There is only one thing (which has nothing to do with your filter) left. The preview is now in someway compressed.


What has happened there with the prerelease?
I now will go to work with the batch.

Thank you so much for this filter.

Pit

The update filter button worked for me. Clean Text now has 4 sliders.

@Pit-Lip definitely there so keep refreshing list, wasn’t there for me last night but it’s there now.

Yes, now everything is there. Perfect!

One can improve further with high pass filter in overlay mode (sharpening) and final desaturation to remove any yellowish color trace.
