The ROC curves for the delineation based on sTrCG, (the average similarity of parameters TrCG and Diffp), (the average similarity of parameters TrCG, Diffp, and Tr0), and (the average similarity of all parameters) for the similarity threshold 90–98%, step 0.5%. The red value is the similarity threshold for which the best sensitivity and specificity results were obtained.
