The following figure investigates the effect of using additional information from neighboring voxels on the quality of reconstructions.
For each method, we compared the distributions of the average angular errors θ obtained on the IV (left bar) and SF (right bar) phantoms. To be sensitive to this effect only, we considered a subset of voxels with two fiber populations from both datasets and we matched the distributions of the crossing angles. We compared the results corresponding to low and high noise levels, respectively with SNR=30 (top) and SNR=10 (bottom).
