Number of fiber populations¶

The following plots present the detailed performance of each method with respect to the estimation of the number of fiber populations in a voxel. The performances are reported both considering the raw estimated fiber directions, metrics $SR$ , $n^+$ , $n^-$ , and also using a tolerancer cone, metrics $SR_{\angle}$ , $n^+_{\angle}$ , $n^-_{\angle}$ .

The average scores are plotted as a function of the crossing angle, where the angle between the two fiber populations was increased from $0^\circ$ to $90^\circ$ .

To help the reader in highlighting differences and similarities among the algorithms, the scores are also summarized in three separate ranges of crossing angles: $0^\circ–30^\circ$ (downward triangles), $31^\circ–60^\circ$ (squares) and $61^\circ–90^\circ$ (upward triangles).
