Table 7. Comparison of the proposed method (SegNet) to the previously reported A-line CNN-based approach [18]. In almost all cases, the new method outperformed, with particularly large improvements in sensitivity, Dice, and Jaccard. Using the Wilcoxon signed-rank test, we determined statistically significant differences (p < 0.05) between the two methods in many instances, as indicated by an asterisk (*).
