Why Do Video Diffusion Models Violate Physics? Unveiling the Flaws in Attention Mechanisms
Yueyan Li, Haibo Wang, Caixia Yuan +1
Despite impressive visual quality, state-of-the-art video diffusion models often generate content that violates real-world physical laws. While existing solutions rely on external…
Learning Geometric Representations from Videos for Spatial Intelligent Multimodal Large Language Models
Haibo Wang, Lifu Huang
Multimodal Large Language Models (MLLMs) excel at 2D semantic understanding but lack intrinsic 3D awareness, resulting in representations that fail to maintain geometric and spatia…
Open-Ended Video Game Glitch Detection with Agentic Reasoning and Temporal Grounding
Muyang Zheng, Tong Zhou, Geyang Wu +3
Open-ended video game glitch detection aims to identify glitches in gameplay videos, describe them in natural language, and localize when they occur. Unlike conventional game glitc…
GLANCE: A Global-Local Coordination Multi-Agent Framework for Music-Grounded Non-Linear Video Editing
Zihao Lin, Haibo Wang, Zhiyang Xu +7
Music-grounded mashup video creation is a challenging form of video non-linear editing, where a system must compose a coherent timeline from large collections of source videos whil…
Think, Act, Build: An Agentic Framework with Vision Language Models for Zero-Shot 3D Visual Grounding
Haibo Wang, Zihao Lin, Zhiyang Xu +1
3D Visual Grounding (3D-VG) aims to localize objects in 3D scenes via natural language descriptions. While recent advancements leveraging Vision-Language Models (VLMs) have explore…
