EgoCross
A comprehensive benchmark across Surgery, Industry, Extreme Sports, and Animal Perspective. EgoCross comprises 798 clips and 957 QA pairs, supporting both CloseQA and OpenQA formats for fine‑grained evaluation.
EgoCross is a cross-domain benchmark designed to evaluate how well multimodal large language models (MLLMs) generalize to egocentric video question answering (VQA). Unlike prior daily-life datasets, EgoCross focuses on diverse and challenging domains — including surgery, industrial assembly, extreme sports, and animal perspective — to assess model robustness under varying visual and semantic conditions.
The benchmark covers 15 sub-tasks grouped into four capability families: Identification, Localization, Prediction, and Counting. Each video clip is paired with multiple close-ended and open-ended questions that require fine-grained temporal, spatial, and reasoning understanding.
In total, EgoCross contains 798 video clips and 957 QA pairs, curated through a semi-automatic pipeline combining LLM-based question generation and human verification. It provides a unified platform for measuring cross-domain generalization, highlighting the gap between everyday understanding and complex real-world egocentric perception.
