Evaluating a segmentation with an incomplete ground truth. (a) Volume visualization of raw KESM data showing microvessels in the mouse brain. (b) The complete test case compared to an incomplete ground truth. Red fibers indicate tracked vessels not present in the ground-truth model. (c) Fibers culled by setting a geometric error threshold of 0.9. (d) Geometric error in the ground-truth model. The connectivity graph is shown for the (e) ground-truth and (f) test-case. Red and green arrows indicate breaks in the test-case fibers, resulting in connectivity errors. Black arrow indicates an incorrectly mapped edge.
