Results on the two EXACT’09 data sets with the highest leakage count and volume when compared to the EXACT’09 reference standard segmentations. For comparison, we performed on the same data sets an evaluation of the segmentation results using independent expert branch-by-branch assessment as described in Section V-A. Airways classified as correct are shown in green, airways classified as leakage are shown in red. (a) CASE34 when compared to EXACT’09 reference standard (leakage count = 206). (b) CASE36 when compared to EXACT’09 reference standard (leakage volume = 4565.3 mm3). (c) CASE34 analyzed by independent expert (FPR = 3.08%). (d) CASE36 analyzed by independent expert (FPR = 1.78%). Renderings of the airway in (c) and (d) are based on the centerline and radius estimate information only, while the renderings in (a) and (b) are based on voxel-accurate delineations of the airway lumen.
