Hi,

Is it possible to skeletonize a binary 2D shape such that its skeleton is defined on a neighbourhood of 8 pixels?

When skeletonizing with :**morphology.medial_axis()** , I tried two structuring elements (se8 or se4) as mask :

The skeletons returned using se8 or se4 are very similar and look defined on a neighbourhood of 4 pixels (left). To me, this is a problem when trying to label the skeleton edges (right).

When skeletonizing with :

se8 = np.array([[True,True,True],[True,True,True],[True,True,True]])

se4 = np.array([[False,True,False],[True,True,True],[False,True,False]])

imK = makeLetterImage('K', 70)

skel =**morphology.medial_axis**(imK,mask=se8)

Ep_Bp, Bp_Bp, Bp, Ep = SkeletonDecomposition(skel)

se4 = np.array([[False,True,False],[

imK = makeLetterImage('K', 70)

skel =

Ep_Bp, Bp_Bp, Bp, Ep = SkeletonDecomposition(skel)
