Yes. But in manual mode, the process of inverting the "defect" through subtraction is complicated for explanation (overflow 0-255). Therefore, in the article inverting is done through multiplication/division. But in the script it has already been implemented through subtraction.

PS: If the GIMP has the application modes "Diff" and "Patch", everything would be much easier. But there are no such modes.

PS2: It seems to me that I poorly understand the question asked (Google-translit).

Hi all.


Draft script used GRAIN-EXTRACT-MODE. GRAIN-EXTRACT-MODE overlay was used for both diff and patch, which greatly simplified the scheme.
