Grounding Video Reasoning in Physical Signals

Alibay Osmanli, Zixu Cheng, Shaogang Gong

Physical video understanding requires more than naming an event correctly. A model can answer a question about pouring, sliding, or collision from textual regularities while still…

Uncertainty-quantified Rollout Policy Adaptation for Unlabelled Cross-domain Temporal Grounding

Jian Hu, Zixu Cheng, Shaogang Gong +4

Video Temporal Grounding (TG) aims to temporally locate video segments matching a natural language description (a query) in a long video. While Vision-Language Models (VLMs) are ef…

V-STaR: Benchmarking Video-LLMs on Video Spatio-Temporal Reasoning

Zixu Cheng, Jian Hu, Ziquan Liu +3

Human processes video reasoning in a sequential spatio-temporal reasoning logic, we first identify the relevant frames ("when") and then analyse the spatial relationships ("where")…

CoS: Chain-of-Shot Prompting for Long Video Understanding

Jian Hu, Zixu Cheng, Chenyang Si +2

Multi-modal Large Language Models (MLLMs) struggle with long videos due to the need for excessive visual tokens. These tokens exceed massively the context length of MLLMs, resultin…
