Branching points in a VORONOI DIAGRAM

I want to make a branching points(red dots) in the given binary image which will be determined as image pixels which are connected to atleast three segment of the given voronoi .

diagram. I want to make a shortest path from the branching points(red dots ) to the start and stop points (white dots).

There is a shortestpath() function.

Also see Steve's blog if you want to work on the image itself

Thank you so much for the reply sir. Sir is there any function to know this branching points, I used this command

[I,J]= find( bwmorph(HW,'branchpoints') )

it gave me I points but how should I show it up i.e, the red dots I had made in the matlab.

i need to use this branching points
