Confrontation sample generation method and device, equipment and medium

The invention provides an adversarial sample generation method and device, equipment and a medium, and relates to the technical field of computer vision. The method comprises the following steps: acquiring a face image of an attacked person; determining a feature region and a feature image of the face image of the attacked person according to the face image of the attacked person; acquiring a face image of an attacker; positioning an attack area of the attacker face image according to the feature area; generating an attack image corresponding to the attack area according to the feature image; and fusing the attack area of the attacker face image with the attack image to obtain a fused image, and generating an adversarial sample according to the fused image. According to the adversarial sample generation method, device and equipment and the medium, the feature image of the face image of the attacked person is generated based on the generative network, more face information of the attacked person is concentrate
