Hard No-Box Adversarial Attack on Skeleton-Based Human Action Recognition with Skeleton-Motion-Informed Gradient

1 code implementation • ICCV 2023 • Zhengzhi Lu, He Wang, Ziyi Chang, Guoan Yang, Hubert P. H. Shum

Specifically, we first learn a motion manifold where we define an adversarial loss to compute a new gradient for the attack, named skeleton-motion-informed (SMI) gradient.
