TABLE II.

Comparison (using the mean Dice index) of several possible combination of patch-based approaches (using optimal global parameter setting) on the IBSR dataset. When structures are separated into left/right, two overlap scores are reported. For the pair-wise results, labels have been fused using the majority voting rule. Highest overlap rates are shown in bold.
