Schematic illustration of the reassignment of voxel-nodes after fractionation of ROIs due to aggregation, (A–F) provides examples of AILP decisions during random selection of voxel-nodes (circled in red) for re-evaluation of group membership. (A) Three of the voxel's neighbors are orange and one is blue, so it is assigned to the orange cluster, (B) five of the voxel's neighbors are blue, one is orange and one is green, it remains in the blue cluster, (C) one of the voxel's neighbors is yellow and one is blue (a tie), it is randomly assigned to one of the two clusters (let us assume blue). (D/E) the voxel's neighbors are blue, it is assigned to the blue cluster. (F) Convergence.
