How Do I Obtain Information About Adjacent Connected Domains?

william-silversmith commented 1 month ago

Hi! I'm not sure what information you are looking for exactly, but take a look at cc3d.contacts for measurements of contact surface area between adjacent regions.

# Compute the contact surface area between all labels.
# Only face contacts are counted as edges and corners
# have zero area. To get a simple count of all contacting
# voxels, set `surface_area=False`. 
# { (1,2): 16 } aka { (label_1, label_2): contact surface area }
surface_per_contact = cc3d.contacts(
  labels_out, connectivity=connectivity,
  surface_area=True, anisotropy=(4,4,40)
)
