Comparison between the Freesurfer parcellated label map and the updated one after applying our algorithm (Optimizing Freesurfer label map section). A part of the brain with low FA labeled as WM (b) is relabeled to GM (c). A part of the brain with high FA originally labeled as GM (e), but is relabeled to WM (f) using our method. Note that in subfigures (b, c, e, f) the images on the left side visualize crisp labels, which are transparent on top of FA on the right side.
