Affordance-Guided Diffusion Prior for 3D Hand Reconstruction
Naru Suzuki, Takehiko Ohkawa, Tatsuro Banno +3
The paper presents a diffusion-based generative prior that refines 3D hand pose reconstruction by using affordance-aware textual descriptions of hand‑object interactions, improving…
SocialDirector: Training-Free Social Interaction Control for Multi-Person Video Generation
Liangyang Ouyang, Ruicong Liu, Caixin Kang +2
Video generation has advanced rapidly, producing photorealistic videos from text or image prompts. Meanwhile, film production and social robotics increasingly demand multi-person v…
AssemblyHands-X: Modeling 3D Hand-Body Coordination for Understanding Bimanual Human Activities
Tatsuro Banno, Takehiko Ohkawa, Ruicong Liu +2
Bimanual human activities inherently involve coordinated movements of both hands and body. However, the impact of this coordination in activity understanding has not been systemati…
Generative Modeling of Shape-Dependent Self-Contact Human Poses
Takehiko Ohkawa, Jihyun Lee, Shunsuke Saito +7
One can hardly model self-contact of human poses without considering underlying body shapes. For example, the pose of rubbing a belly for a person with a low BMI leads to penetrati…
Leveraging RGB Images for Pre-Training of Event-Based Hand Pose Estimation
Ruicong Liu, Takehiko Ohkawa, Tze Ho Elden Tse +3
This paper presents RPEP, the first pre-training method for event-based 3D hand pose estimation using labeled RGB images and unpaired, unlabeled event data. Event data offer signif…
SiMHand: Mining Similar Hands for Large-Scale 3D Hand Pose Pre-training
Nie Lin, Takehiko Ohkawa, Yifei Huang +5
We present a framework for pre-training of 3D hand pose estimation from in-the-wild hand images sharing with similar hand characteristics, dubbed SimHand. Pre-training with large-s…
