I have bw 4-connectivity images where some lines are too thick and I am looking for a method to thinning them but preserving 4-connectivity.
So far I only find the bwmorph 'skel' option but it converts to 8 connectivity.
This is part of the original image. Please notice the bottom double thick segments.
Result after bwmorph(BW,'skel');
Is there any similar function for thinning the lines but preserving 4-connectivity?

There does not seem to be an option to skeletonize with bwskel or bwmorph to create a skeleton with 4-connectivity. It looks like 8-connectivity is the only option. Why do you need an option to have it be 4-connected?

When I asked "Why?", you basically said "because it does", which is not an explanation.
You can just scan the image and if you find certain patterns, like a diagonal pattern, to fill in a pixel. There should be just a handful of possible patterns that are not 4-connected.
