  1. Comparing the developed method with the three state-of-the-art separation methods using a one-sided paired t test in the database T1. Each cell show the parameter p that represents the probability of setting a statistically significant result. Considering a confidence interval of 95%, small values of p < 0.05 indicate that there exists statistical significance of the results evaluated.
