Figure 5
Estimation of mean and covariance tensors from synthetic MR signal without noise. The estimation is shown for three different DTDs (isotropic emulsion, shape heterogeneous and crossing fiber type DTDs) shown in Figs. 2 and 3. The signal curve using the proposed model obtained from actual and estimated mean/covariance tensors is shown in the first row. The mean and covariance glyphs for actual (orange) and estimated (blue) DTD are overlaid and shown in the second row. The above graphics was generated using the matplotlib package68, and the Mathematica software67.
