Hi users,

  I am trying to find the tortuosity of a material(3D) In x,y,z directions.

1)As a first step I skeletonized the pores.
2)I used analyze skeleton in imagej to get the vertexes and the edges.

How do i identify the shortest path from this ? how do i draw all the possible paths in a graph and find the tortuosity  distribution in all three directions?
