PhotoHOI: Synthesizing 3D Hand-Object Interactions from a Single RGB Photograph
Zhenhao Zhang, Jiajun Zhang, Wei Min +1
Hand-object interaction (HOI) is a fundamental human behavior with broad applications in AR/VR, digital humans, and embodied interaction. Existing methods typically require predefi…
GAF: Gaussian Action Field as a 4D Representation for Dynamic World Modeling in Robotic Manipulation
Ying Chai, Litao Deng, Ruizhi Shao +6
Accurate scene perception is critical for vision-based robotic manipulation. Existing approaches typically follow either a Vision-to-Action (V-A) paradigm, predicting actions direc…
SharpTimeGS: Sharp and Stable Dynamic Gaussian Splatting via Lifespan Modulation
Zhanfeng Liao, Jiajun Zhang, Hanzhang Tu +4
Novel view synthesis of dynamic scenes is fundamental to achieving photorealistic 4D reconstruction and immersive visual experiences. Recent progress in Gaussian-based representati…
ManiVideo: Generating Hand-Object Manipulation Video with Dexterous and Generalizable Grasping
Youxin Pang, Ruizhi Shao, Jiajun Zhang +5
In this paper, we introduce ManiVideo, a novel method for generating consistent and temporally coherent bimanual hand-object manipulation videos from given motion sequences of hand…
