SituHOI: Scalable Capture of Scene-Situated Full-Body Human-Object Interaction
Qifan Wang, Qihang Fang, Boao Shi +4
Modeling human-object interaction (HOI) in real environments requires jointly representing whole-body motion, manipulated objects, and scene geometry, yet existing datasets trade o…
HuMoCon: Concept Discovery for Human Motion Understanding
Qihang Fang, Chengcheng Tang, Bugra Tekin +2
We present HuMoCon, a novel motion-video understanding framework designed for advanced human behavior analysis. The core of our method is a human motion concept discovery framework…
CigTime: Corrective Instruction Generation Through Inverse Motion Editing
Qihang Fang, Chengcheng Tang, Bugra Tekin +1
Recent advancements in models linking natural language with human motions have shown significant promise in motion generation and editing based on instructional text. Motivated by…
BID: Boundary-Interior Decoding for Unsupervised Temporal Action Localization Pre-Trainin
Qihang Fang, Chengcheng Tang, Shugao Ma +1
Skeleton-based motion representations are robust for action localization and understanding for their invariance to perspective, lighting, and occlusion, compared with images. Yet,…
