k_{lin e} in Eq. 3 was chosen as 2.5 (presented in parenthesis). Increasing values of k_line reduced the sensitivity (S) of the threshold thresh_line/t, whereas decreasing values decreased the precision (P). Variations in these two indexes affected the Accuracy (Acc) and the Specificity (SP). k_line = 2.5 is a good compromise between S and P.
