Shown are several of the features used in our approach, including the T1-w intensity (IT1(x)), T2-w intensity (IT2(x)), fractional anisotropy (F(x)), mean diffusivity (M(x)), edge map (|G(K(x))|F), the multi-atlas prior (P(x)), and two of the Knutsson space components (K1(x) and K5(x)). The red outline indicates the manually delineated ground truth.
