Attack strategy #1 attack on the monitor screen: image perturbations are added on the original image to create an adversarial example, which is displayed on the monitor screen to cause misclassification; Attack strategy #2 attack on the secondary surface: wall perturbations are added on the secondary surface to change the measured image and cause misclassification.
