Small blobs with bad conditioned topology are not skeletonized. This because all the voxels in these kind of blob represent a independent junction. After the merging process, all the voxels give rise a single isolated junction (node). Consequently, these blobs are mapped into nodes of degree zero and excluded from the final skeleton. In principle, these blobs could be detected by searching for connected component in which there are no transitive voxels. Transitive voxels are those that have exactly two neighbors after the thinning process.
