Abstract:

The security vulnerability of deep learning models to carefully crafted adversarial attacks has garnered significant attention. Although existing defense methods against adversarial attacks have made some progress, they still suffer from poor generality, exhibiting strong defense performance against specific attack types while showing limited or ineffective protection against others. This paper proposed a universal defense method based on a Transformer architecture for super-resolution networks. First, the dynamic enhancement of high-frequency image information was achieved through self-attention mechanisms to improve image quality. Second, multi-scale feature fusion techniques were employed to effectively suppress adversarial perturbations. Finally, an innovative diversified window partitioning strategy was introduced, significantly reducing computational complexity while maintaining long-range pixel dependencies. Experimental results demonstrate that the proposed method achieved an average defense success rate of 90% against multiple attack types, surpassing existing baseline methods while exhibiting stronger robustness.
