Diffusion-Weighted Images Superresolution Using High-Order SVD

Figure 5

FA maps estimated using the gold standard and several other methods. (a) FA maps estimated using the gold standard; FA maps obtained for the reconstructed dataset using the (b) B-spline, (c) nonlocal method, (d) the proposed HOSVD, and (e) the proposed HOSVD-M. Enlarged details of the (f) golden standard, (g) B-spline reconstruction, (h) nonlocal method, (i) the proposed HOSVD, and (j) the proposed HOSVD-M. The red ROIs indicate a detailed reconstruction. Visually, the FA map obtained using the proposed method is closer to the FA of the gold standard. FA residual of the (k) B-spline, (l) nonlocal method, (m) the proposed HOSVD, and (n) the proposed HOSVD-M.
