$$ \begin{array}{ccc} \times & 1 & \times\\ \times & 1 & \times\\ 1 & \times & 1 \end{array} ~~~~~~~ \begin{array}{ccc} 1 & \times & \times\\ \times & 1 & \times\\ 1 & \times & 1 \end{array} $$
Segmentation of particles:
In the following figure, it is possible to differentiate particles by counting their number of triple points (in black) and their number of extremities (in gray).
