Fig. 7

Set the brightness (a) or contrast (b) of all the CXRs in the held-out test dataset to 1.0, then negative and positive brightness or contrast changes with increments and decrements of 0.1 were tested. It was obvious that small changes in brightness and contrast had little effect on the performance of the YOLOX model. mAP: mean average precision, IoU-T: intersection over union threshold.
