Results of the matched resolution scanner-to-scanner mapping: Global MSE for FA, MD, R0, and R2 (columns); for the 4 different test subjects; for predictions of the 80 mT/m data (top, open circles) and the 300 mT/m data (bottom, closed circles). The different methods are represented with different colours SHNet (blue), SHResNet (red), SphericalNet (orange), FCSNet (purple), SDL (green), and reference (black). The reference results for different subjects are connected with lines as a visual aid to compare with the performance of the proposed algorithms. The range of scan-rescan MSEs across three subjects is shown by the gray rectangle. The scan-rescan result for the only overlapping subject “H” is indicated by the *.
