Fig. 4.

Visualizations show 500 random streamlines for each technique. Left most image shows ground truth connectivity. Based on visual inspection, iFOD1, iFOD1 (-rk4) and iFOD2 techniques do not preserve the organization of the fiber bundles as well as the SD_STREAM and the proposed algorithm. This is better observed in the zoomed regions that show the fiber crossing area marked with blue rectangles. Tractometer scores of the displayed tractograms (using all of the 100 thousand streamlines) are shown in Table I. Caption of Table I also writes the parameters used to generate the streamlines. No downsampling is done on the streamlines.
