pycroglia.core.slimskel3d.tests.unit.test_graph2skel.test_graph2skel()

Test Graph2Skel3D correctly reconstructs skeleton from graph.

Asserts:

• Converting a skeleton volume to graph (skel2graph) and back to a voxel skeleton (graph2skel) matches the original volume except for 9 known mismatched voxels.

• The number of mismatches is exactly 9.

• The mismatched voxel coordinates match the expected set.

pycroglia.core.slimskel3d.tests.unit.test_skel2graph.test_skel2graph()

Test Skel2Graph3D correctly converts a skeleton volume to a graph.

Asserts:

• The number of detected nodes equals 88.

• The number of detected links equals 97.

• The computed adjacency matrix matches the expected adjacency matrix (loaded from file) element-wise.

pycroglia.core.slimskel3d.tests.unit.test_skeleton3D.test_skeleton3D()

pycroglia.core.slimskel3d.tests.unit.test_slimskel3d.test_slimskel3d()

Test that slimskel3d prunes short spurs while preserving main branches.

This test constructs a synthetic 10×10×10 volume containing:

• A main vertical skeleton branch along the z-axis at coordinates (y=5, x=5).

• A short 2-voxel spur branching in the +x direction at z=5.

Assertions:

• The number of voxels after slimming is strictly less than before, ensuring spur pruning occurred.

• The set of remaining voxel coordinates matches the expected slimmed skeleton:

  [[2, 5, 5],

  [3, 5, 5], [4, 5, 5], [6, 5, 5], [7, 5, 5],
