Figure 2

Illustration of clustering steps within one hierarchical level. Four subjects are used as examples. (a) The corresponding parcels in brown color are the parcels in consideration at the current level. The numbered bubbles denote nine DICCCOLs; (b) Adaptive AP clustering results based on DICCCOL samples. DICCCOLs are clustered into four classes and they are of the same color if they are within the same class; (c) Propagating clustering labels obtained from DICCCOLs onto other vertices within the parcels in consideration via a group-wise classification algorithm. Surface vertices within the same class are of the same color; (d) Updating DICCCOLs classification results based on vertices propagation results. DICCCOL #2 highlighted in (c) and (d) are assigned to the green-color class after updating.
