This curve is extracted from Figure 3, it connects the convergence values of the energy function of the segmentation problem, of the sample in Figure 1, by considering different values of the variable n in Equation (2), with the same random initialization matrix for all n values, and with a pre-specified convergence time Ts = 120 iterations.
