Table 5:

Comparison of performances achieved on the MICCAI 2012 dataset using our method and FreeSurfer. The p-value showed the statistical results of the repeated-measures t-test, indicating a significant improvement of segmentation accuracy for most of the structures, except for the caudate and hippocampus.
