This study benchmarks Vision-Language Models (VLMs & VLLMs) on five ADL video tasks across 11 datasets, revealing their struggles with fine-grained action understanding. Despite their web-scale success, these models fall short on real-world, densely labeled, and long-video challenges.

SKI models integrate 3D skeletons into vision-language models using SkeletonCLIP, enabling improved generalization to unseen actions in ADL videos. They enhance robustness by not requiring skeleton data during inference and show effectiveness in zero-shot action recognition and video captioning.

MS-Temba adapts Mamba-based state-space modeling to Temporal Action Detection by introducing dilated multi-scale SSMs that capture both fine-grained and long-range temporal dynamics in long, untrimmed videos. Through scale-aware supervision and a dedicated multi-scale fusion module, it delivers precise localization of densely overlapping actions and generalizes effectively to long-form Video Summarization.
