Figure 10.

The results of different evaluation metrics of the two-level approaches and the three sparsifying schemes. The two-level approaches, i.e., the two-level MSC approach and the two-level SLIC approach, with and without overclustering (OC) are displayed for comparison. The four rows correspond to the difference between the actual cluster number and the initialized cluster number, the functional homogeneity, the group-to-group reproducibility, and the group-to-subject reproducibility in order. The three columns correspond to SS1, SS2, and SS3 in order.
