Question on the output of contacts about connected-components-3d HOT 9 CLOSED

Yup, that looks like a bug to me. Let me check it out.

from connected-components-3d.

I've just uploaded a new version to PyPI! Please give it a test and let me know if that solves it for you.

from connected-components-3d.

Yes, it solves the problem and the results now make more sense to me.
Btw, would it be possible to implement a periodic boundary condition? I understand that experimental images may not consider it, but having this option for simulations would be cool.
Thank you again for solving this issue!

Hi,

It means that D(x)=D(x+L), where L is the length of the box along x, so that in the following case:

data = np.array([[3,3,0,3,3]])
labels_out = cc3d.connected_components(data, connectivity=6)

Thereby instead of array([[1,1,0,2,2]], dtype=unit16) it will output array([[1,1,0,1,1]], dtype=unit16) if periodic boundary condition is applied.
Maybe this wiki would be helpful in explaining what I meant.

Oh I see what you mean. That's an interesting application. I'll consider it.

Would you need support for 6 connected only? It's a lot more tractable to support it for a limited number of connectives. I believe there are 8 separate CCL implementations in the codebase: 4, 8, 6, 18, 26, and three continuous domain versions. I don't think I'd have time to do more than a few of them.

Might be good to continue this conversation here: #117

Thank you! I think 6 should be enough.
