Tail-beat Shown in Clustergram
If a clustergram is formed with Background Subtraction enabled and Motion Detection not enabled, we may get an image as shown above. "Raw" data are plotted in a clustergram format. In this case, the "feet" of the "centipede" indicate tail-beats. Tail-beat frequency can be determined by the number of these beats over a selected number of image frames. Tail-beat frequency is a clue for species identification.
