Researchers introduced AnyGroundBench, a domain-adaptation benchmark for evaluating video grounding in vision-language models across five specialized domains: animal, industry, sports, surgery, and public security.
The benchmark evaluated 15 state-of-the-art VLMs on both zero-shot generalization and In-Context Learning capabilities, using newly captured expert-annotated videos paired with established datasets for dense spatio-temporal annotations.
Findings reveal current models fail significantly in both zero-shot and ICL-based adaptation when confronted with specialized domains, exposing critical flaws in spatio-temporal reasoning that future research must address.
