Visual comparisons of lung infection segmentation using different algorithms. The green and the yellow areas represent the undetected and detected true infection regions, respectively. The red areas indicate the false infection regions that are incorrectly detected. (a) The original CT images from the test set. (b) The corresponding ground truth for each image. (c-j) The corresponding segmentation results from the eight state-of-the-art models. (k) The segmentation maps of the proposed PGPLP.
