the source code of the StylePatch（a adversarial patch attack method using the local style fusion）
StylePatch is an approach to enhance the stealthiness of adversarial patches through a framework founded on local style fusion. This methodology commences with the identification of image areas susceptible to perturbation, accomplished through weighted class activation mapping, facilitating precise localization of the optimal placement for adversarial patches. Employing style transfer techniques, the framework computes style and content matrices between the target image and the adversarial patch. During the adversarial patch generation process, the adversarial patch's style and content are refined using the cosine distance function to enable seamless fusion with the style and content of the local image it overlays. This integration into the ambient environment results in color and style harmonization, thereby mitigating the patch's perceptibility to the human visual system. The overarching objective is to amplify the covert nature of adversarial patches. Experimental findings affirm the utility of this approach, as it engenders adversarial patches characterized by both clandestine attributes and effectiveness, enabling surreptitious attacks imperceptible to human observers.
