Left column comprises the original benign microcalcification images. The right column shows the Grad-CAM results overlaid on the heatmap on the original images. The upper-left image shows grouped amorphous microcalcification and lower left image shows segmental amorphous microcalcification. The upper-right image illustrates a true negative (TN); the lower-right, a false positive (FP). The Grad-CAM results were generated by the Inception-ResNet-v2 model. The red and blue areas depict the activated and less-activated regions, respectively.
