Figure 4:

Semiquantitative analysis results for (A) cardiomegaly (orange contours were predicted lung masks and green contour was predicted heart boundary; these were used to calculate the cardiothoracic ratio), (B) pneumothorax (orange contours were predicted lung masks and green contour was predicted lung masks with lung texture; these were used to calculate the area compression degree), and (C) pleural effusion in frontal chest radiographs (red contours were ground truth and others were outputs of the model; these were used to calculate effusion level and confidence score).
