Iterative thinning skeletonization methods can provide a distance in voxels from each tree node to the surface of the object. This distance is the D6 metric, obtained by counting the number of voxels as they are removed in the minimal 6-connected path from the surface to the medial axis.
Iterative thinning skeletonization methods can provide a distance in voxels from each tree node to the surface of an object. This distance is the D6 metric, calculated by counting the number of voxels removed along the shortest path connecting the surface and the medial axis.
