Very nice article.
When I was studying I really liked my classes about signal processing. When I was reading your article I felt as I went back in time. 😁
I'm not sure if you have heard about salt and pepper? It's related to additional dots on an image. There are several techniques for removing such a noise like median filter. Maybe it would give even betterer results.

Thank you for your post.

Thanks!
Yes, I know about the median filter. Very recently had a semester long course in image processing. I had implemented region growing with this, to get great noise free skeletons. Will try with the median filter!
