Hi,
I want an approach and method to separate the connected lines. Here is my image
and here is the result I would like
How do I solve that problem? Thank you in advance!
Sincerely

Will the place you break always be on a "vertical" segment?
I think Regionprops and some heuristics will allow you to do this reasonably. Any a priori knowledge is useful to allow you to make this algorithm.

call bwmorph to get branchpoints. Then remove then. Then get the endpoints of the segments and compute the angle. Remove any segments that are more vertical than horizontal. Then replace the branchpoints.
