SC-Net: Salient Point and Curvature Based Adversarial Point Cloud Generation Network

Zihao Zhang, Nan Sang, Xupeng Wang, Mumuxin Cai

ICASSP 2023accepted

Deep neural networks for 3D point clouds are receiving increasing attention. Recent works have shown that deep neural networks for 3D point clouds are vulnerable to adversarial attacks. However, existing adversarial attacks typically iteratively optimize a single sample to generate the adversarial p…
