Table 5 Values obtained in PG, CZ and PZ regions of interest using ground truth original and predicted masks. “mask” and “predicted” in the column headers refer to the ground truth and model output, respectively. T-test results between ground truth and predicted masks for PG, CZ and PZ are also reported in the right part of the table (based on segmentation results from UM and input images of mag).
