Table 3.

Comparison results on PFV segmentation. Our methods outperform existing methods in terms of mean DSC and MSD. The statistical analyses were conducted between the previous methods and the proposed methods.

Methods	FreeSurfer	SPM12	MV*	NLSS*	nssSLANT	ssSLANT
DSC	N/A	N/A	0.960	0.968	0.975	0.977
MSD	N/A	N/A	0.847	0.675	0.554	0.542

The methods with significant difference (p < 0.05) are marked with ‘*’. The statistical analysis is not conducted on FS and SPM12 in this Table, since they do not provide hard posterior fossa segmentation. All benchmarks were run on brain with skull.
