Visualization of attention maps from COPD research (IMAGE)
Caption
Visualization of attention maps from the residual attention networks for the inspiratory convolutional neural network (I-CNN) and expiratory convolutional neural network (E-CNN) models. Attention maps highlight regions of the input image contributing to the network’s predictions. Low-level features (minor details, such as texture) and high-level features (major details, such as shape) are displayed overlaying a single coronal section of the original input noncontrast CT images. Overlay color indicates strength of attention (ie, strength of contribution) ranging from low attention (blue) to high attention (dark red). One example for each Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage is shown.
