11 // 1. peek the most energetic cell
12 // 2. assign it as a center of the cluster and add cells surrounding it: 3x3, 5x5...
13 // 3. remove the cells contributing to the cluster
14 // 4. start from 1 for the remaining clusters
15 // 5. cluster splitting (not implemented yet) - use the shape analysis to resolve the energy sharing
16 // - for high energy clusters check the surrounding of the 3x3 clusters for extra energy
17 // (merge 3x3 clusters and resolve the internal energy sharing - case for 2 clusters merged)
