It is not a case of the image posted. The problem is your requests are not easily fulfilled using Gimp / Inkscape / Krita.
Just to get a mass of overlapping dots separated from a mass of half visible connecting lines to try and get a centerline trace out of Inkscape is almost impossible, needs a lot of preparation for a less-than wonderful result. - that was one of your requests.
You would be better off finding some other way.
