Fig. 6. Parameter Maps computed with local MAP STAPLE for one IBSR Segmentation.

Fig. 6

Local parameter map (sensitivity) and its relative uncertainty for the right post-central gyrus of one subject projected on a target subject. (a): Anatomical image of the projected subject, (b): Segmentation of the post-central gyrus for the projected subject, (c): Local MAP STAPLE reference standard obtained from the 17 projected segmentations (including (b)), (d): Local parameter map for local MAP STAPLE. (e): Confidence bounds for the parameters shown in (d) (in percentage of the estimated value). Color bars show respectively the scale of the parameter map and relative uncertainty map (in percentage of the estimated parameter value). The local sensitivity map of this representative input segmentation varies widely across the image. Local variation in segmentation performance is identified by local MAP STAPLE but not by majority voting or STAPLE.
