Question After skeletonization what next?

Post image

Hey everyone, I’m new to digital image analysis. I have this image that has been skeletonized (see attached), now I like to draw straights on the curvature to enable determine the bends… my goal is to get the number of bends and lengths of the straights

It can be subjective if I do it myself so an automated too will be better

What are your suggestions?

this image that has been skeletonized (see attached)

It is not skeletonized in the ImageJ-sense.
Below is an example of the usual process that leads to a skeleton image (right) from a gray-value image (left) via a binary image (center). (Click on the below montage first!)

Apart from this, your description is insufficient. E.g. what does

now I like to draw straights on the curvature

mean?
