Iteration 1: first graph-cuts run; easy groups are correctly clustered while the most complex still present errors (the FCG formed by P7 and P20 violates the visibility constraint). Iteration 2: the second graph-cuts run correctly detects the O7,8,9 F-formation (at the bottom). Se text for more details. ER -
