Table 1.

Achieved results showing the median Dice similarity coefficient (DSC), the Intersection-over-Union (IoU) the sensitivity (Sens) and specificity (Spec) on Lung and COVID-19 infection segmentation for each k-fold cross-validation of the sensitivity analysis for the Ma et al. and An et al. dataset. Standard deviation is included for DSC and IoU.
