I've been using
Thinning recently on line-like structures in an attempt to generate skeleton-like chains of pixels connected through their Moore neighborhoods.
The description of
Thinning says that the algorithm "finds the skeletons of foreground regions in image by applying morphological thinning until convergence". What does "convergence" mean? If I start with a cluster of pixels connected through their Moore neighborhoods, what am I guaranteed after "convergence"? Will the product always be a chain of pixels also connected through their Moore neighborhoods?
