Hi Gaël,
I don't know if I understand. The idea is to use _make_edges_3d to
give me the connectivity, isn't it? Like for example, a 3x3 image:
0, 1, 2
3, 4, 5
6, 7, 8
If I use _make_edges_3d(3, 3) I get:
array([[0, 1, 3, 4, 6, 7, 0, 1, 2, 3, 4, 5],
[1, 2, 4, 5, 7, 8, 3, 4, 5, 6, 7, 8]])
So, for example, the pixel 4 is connected with 3, 5, 7 and 1
(connectivity 4). Is it?
The problem is I need to work with connectivity 26 in 3D images, or 8
in 2D images. I'm not able to understand the code so well to apply to
those connectivity I said (8 and 26). Do you think it is possible?
Thanks Gaël,
