Table II.
The mean distance errors for surfaces corrected using topological correction are small when compared with the original uncorrected surface
| Correction | Mean distance error (mm) | Hausdorff distance (mm) | ||
|---|---|---|---|---|
| Forward | Reverse | Forward | Reverse | |
| FreeSurfer | 0.227 (±0.006) | 0.408 (±0.005) | 4.186 (±0.037) | 10.592 (±0.075) |
| SPH | 0.011 (±0.000) | 0.309 (±0.002) | 3.031 (±0.018) | 11.025 (±0.037) |
However, the reverse Hausdorff distance is large because of the removal of defects.
