Fig. 5: Visualized segmentation results from different methods.

For every method, the segmentation result for a whole TOF-MRA volume is presented on the middle raw. Then two regions marked by the yellow and gray boxes are zoomed in and then displayed above and below to show details of segmentation. In every sub-figure, true positives are marked in red; false positives are marked in blue; false negatives are marked in green. White arrows point to areas with significant segmentation differences.
