Skeleton-based Zero-Shot Spatio-Temporal Action Localization via Weakly-Supervised Pretraining

Koshiro Nagano, Fumiaki Sato, Ryo Hachiuma +2

We propose a novel pretraining strategy for skeleton-based zero-shot spatio-temporal action localization to estimate unseen actions for person instances while overcoming high annot…
