G'MIC Inpaint Routines

[fern99]

It's said inpainting may be used to repair a damaged photo. G'MIC has 5 different inpaint routines. Between them they have about 2 dozen adjustable parameters. I can't find any basic instruction. Why 5 separate inpaint routines? What are all the parameters for? If anyone could advise a beginner, or point to such advice, it would be appreciated.

That is what mathematicians do, find ways of applying different methods.
The developer David Tschumperlé rarely comes to this forum so you could ask here: https://discuss.pixls.us/

When released this is the comment   quote......There are only few filter parameters to set, but you have to experiment a little bit with them, because finding good parameters depend on the size of the region you want to remove, the resolution of your image, etc. which is very valid, it all depends on the image and degree of damage.

...but for some things, dust marks, tears,  it does work. Very often the default settings are all you need. A quick example, image pulled off internet.  Make sure you paint in a mask with pure red and use the pencil tool (no antialising)

Not quite an answer to the G'Mic-Qt problem, but I couldn't resist using the example Rich used to repair the damaged photo. I used the resynthesizer, the clone tool, the retouch tool, the blur/sharpen tool, and copied some parts of the photo to do some repair. Then I desaturated the photo. It's possible with Gimp and the resynthesizer plugin to get a reasonable result.
