In the published article, there was an error in the legend for Figure 2 as published. The symbols were attributed to the incorrect IDs. The blue triangle—U-Net fn ResNet18—was described as U-7 but should have been U-4. The green star—U-Net fn ResNet50 - was described as U-13 but should have been U-7. The blue square—U-Net fy ResNet18 was described as U-4 but should have been U-10. The green diamond—U-Net fy ResNet50—was described as U-10 but should have been U-13. The order has been rearranged into the numerical order of the IDs. The correct figure and legend appears below.
