Comparison of discovered patterns of the superior temporal gyrus by using (a) the original mean curvature map (L1 to P6), (b) the gyral crest curves (G1 to G4), and (c) the proposed multi-view curvature features (M1 to M4). Herein, patterns L1 to L2 and patterns P1 to P6 are the last hierarchy and penultimate hierarchy clustering results of using the original curvature feature, respectively. As we can see, the proposed method discovered four distinctive folding patterns, while using the original curvature feature or gyral crest curves essentially only discovered two or three distinct patterns, as several patterns are similar among their discovered folding patterns.
