Medial Axis from multiple closed curves, middle of double lines

Hey Everyone, i read through many posts and discussions but could not finde a solution to the problem i am facing. With the plugin Rooster i traced the black and white image to curves but now they are all doubled i only want a polyline or simple lines to represent the picture below. [2] I found a method for finding the Medial Axis but the curves resulting from this are to complex: Image Tracing.gh (277.5 KB) [1] I hope you know a different method to simplify the double curves or the Meda…

For your specific example, you have a lot of overlapping/duplicate curves in your model that would definitely need to be cleaned before starting with GH.
I ran SelDup in Rhino, then removed short curves in GH, and grouped curves by length proximity. It’s not 100% especially around the central wall.
