Fig. 2

Visual example of the average Hausdorff distance (AHD) ranking error. The ground truth image (a) contains no error, (b) contains one error, (c) two errors, and (d) three errors (added errors are indicated with arrows coloured the same as the corresponding error, for a description of the errors see below). AHD misranked (c and d). In contrast, balanced average Hausdorff distance (bAHD) correctly ranked all three segmentations according to the number of errors contained in the images. Green, error representing false positive voxels in the skull area; yellow, error representing voxels removed bilaterally from the internal carotid arteries; blue, error representing voxels added bilaterally to the M1 segment of the middle cerebral artery
