The segmentations of the subject that Semi-local Weighted Fusion performed the worst on. Left to right: FreeSurfer, Global and Semi-local Weighted Fusion. Common mistakes (indicated by arrows): (A) Global Weighted Fusion tends to over-segment complex shapes like the cortex. (B) Semi-local Weighted Fusion does not encode topological information, as FreeSurfer does. Hence it may assign an “unknown” or “background” label (white) in between the pallidum (blue), putamen (pink), and white matter (green).
