Fourier Analysis on Robustness of Graph Convolutional Neural Networks for Skeleton-based Action Recognition

1 code implementation29 May 2023 Nariki Tanaka, Hiroshi Kera, Kazuhiko Kawamoto

Using Fourier analysis, we explore the robustness and vulnerability of graph convolutional neural networks (GCNs) for skeleton-based action recognition.

Adversarial Bone Length Attack on Action Recognition

no code implementations13 Sep 2021 Nariki Tanaka, Hiroshi Kera, Kazuhiko Kawamoto

Specifically, we restrict the perturbations to the lengths of the skeleton's bones, which allows an adversary to manipulate only approximately 30 effective dimensions.
