Black-box Adversarial Attacks Against Image Quality Assessment Models

no code implementations27 Feb 2024 Yu Ran, Ao-Xiang Zhang, Mingjie Li, Weixuan Tang, Yuan-Gen Wang

Specifically, we first formulate the attack problem as maximizing the deviation between the estimated quality scores of original and perturbed images, while restricting the perturbed image distortions for visual quality preservation.

Vulnerabilities in Video Quality Assessment Models: The Challenge of Adversarial Attacks

1 code implementation NeurIPS 2023 Ao-Xiang Zhang, Yu Ran, Weixuan Tang, Yuan-Gen Wang

In this paper, we make the first attempt to evaluate the robustness of NR-VQA models against adversarial attacks, and propose a patch-based random search method for black-box attack.

HVS Revisited: A Comprehensive Video Quality Assessment Framework

no code implementations9 Oct 2022 Ao-Xiang Zhang, Yuan-Gen Wang, Weixuan Tang, Leida Li, Sam Kwong

Based on the revisited HVS, a no-reference VQA framework called HVS-5M (NRVQA framework with five modules simulating HVS with five characteristics) is proposed.
