I am trying to write a c++ code for finding the endpoints and branch points of a skeleton. dose anybody have any idea how to do that using opencv?

Skeleton

asked 2016-07-05 03:29:22 -0600

I am new in working with opencv. I have a binary skeleton result and the result of skeleton has some annoying branches and I want to clean up my skeleton and only preserve the main branches. then I want to trace the line which normally has a bifurcation by DFS. I would appreciate if anybody could help me .

Hint: the endpoints have only one neighbor, the points on the skeleton have two neighbors and the junction points have more than two neighbors (by neighbor I mean active point).

You can track the branches from the endpoints to the nearest junction, and count its length. If it's shorter than a given distance, just delete it.
