Abstract
Facial recognition adversarial patch adjustment is performed by applying a patch to a digital image including image data representing a face to obtain a patched image, applying a face detector to the patched image to obtain a detection value representing a likelihood that the patched image includes image data representing facial features, applying a feature extractor to the patched image to obtain a feature vector, applying a similarity determiner to the feature vector and a target feature vector to obtain a similarity value representing a likelihood that the patched image includes image data representing a target face, calculating a loss based on the detection value and the similarity value, and adjusting the patch based on the loss.
