“…The images are of 0.21m spatial resolution per pixel (zoom level 19) with variable size, some being of size 4500 × 5500 while others being of 1000 × 2000. To compare the segmentation results with the SOTA [71], the split of database is set to be as 14 images for training, 3 images for validating, and 3 for testing the model. For training the proposed network, the 14 training images were randomly segmented into patches of size 512 × 512, then the obtained patches were augmented by applying five different operations: horizontal / vertical flipping and rotation at 90 • , 180 • and 270 • .…”
