Example results of predicted cases, including (a) true positives (TP), (b) false positives (FP), (c) true negatives (TN), and (d) false negatives (FN). The true and predicted lung-opacity regions are denoted by green and red bounding boxes, respectively. Within the definitions of this study, we considered the second example in (a) to be a TP despite one of the two predicted boxes (yellow arrow) not overlapping with the reference box. We regarded the second example in (b) as an FP. Although the CXR model correctly predicted this as positive, the predicted region, indicated by the orange arrow, does not overlap with the green box.
