Contour analysis. Surface maps show mean displacement of automated algorithms compared to manual segmentation (in mm). Significantly larger displacements (i.e., increased segmentation errors) of NLFCM, SPM8, and FSL‐FAST compared to the proposed algorithm, corrected for multiple comparisons using random field theory for nonisotropic images at FWE < 0.01, are highlighted by white borders.
