Schematic diagram of the regions of interest for the right and left lung (R_ROI and L_ROI, respectively) based on the strongest activation of max-pooling layers in the 1-Input convolutional neural network (CNN) model. Conv: convolutional layer; CXR: chest X-ray radiography; MI-CNN: multiple-input convolutional neural network.
