Short title: typical behavior of the number of clusters as a function of the threshold. The figure illustrates the increase in the number of clusters for a given image when increasing the threshold parameter θ. The same behavior is displayed by the number of clusters in all the images, with some slight variations of the actual values not affecting the generic shape of the curve. The upper bound has been set θ = 0.5 rather than θ = ln 2 due to the software limitation of the number of clusters.
