components from (d), is tricky: The marker of the sup-reconstruction is a white
image with a single black point. To detect the red dots from the original color
image, the red channel is selected, and a simple h-maxima filter, with a high
dynamics parameter (e.g., 20), selects the red dots. The dynamic of a regional
maximum is the height we must climb down from that maximum in order to
reach another maximum of higher elevation [13]. Similarly, the dynamic of
a minimum is the minimum height we must climb from that regional minimum
in order to reach a lower regional minimum.
