Accuracy Overview (IBSR)

Accuracy is reported as Dice overlaps between a tool's segmentation and the Internet Brain Segmentation Repository (IBSR) manual segmentation for each of the 18 IBSR subjects. The inter-tool comparison (on the left below) shows the median Dice coefficient for each tissue class. The overlaps for FSL (from which the median values are drawn) are shown in the plot on the right.

Subject Accuracy (IBSR)

Overlap coefficients for each tissue class are shown here for each IBSR subject. Select a subject below to see the FSL results compared to other tools.
