Researchers have introduced five new benchmark datasets—O-UCF, O-JHMDB, OVIS-UCF, OVIS-JHMDB, and Real-OUCF—to study the impact of occlusions on video action detection. The study found that existing models significantly degrade as occlusion severity increases, with performance differing based on whether occluders are static or moving. The research also highlighted that transformers can outperform CNNs in handling occlusions, and incorporating symbolic components like capsules enables models to generalize to unseen occluders. These findings led to the development of effective training recipes that improve occlusion robustness, with models leveraging these recipes outperforming existing video action detectors by up to 32.7% on specific benchmarks.
