Figure 11

Detection of fallen blocks during the experiment of Figure 10: (a) background scenario; (b) size-defined rock block on the target (red frame) and ballast moved due to block rock impact (blue frame); (c) results obtained by the algorithm operation: changes of pixel are detected (red frame) and an alarm signal is send.
