The statistical significance of the results for DM regularized model compared against the baseline model are represented by * and ** for P-values < 0.05 and 0.005, respectively. The best performing model for each metric has been highlighted. SN: SegNet, USN: USegNet, UNet: UNet.
Best performing model for the ED and ES phases are shown in bold case.
