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…
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…
ManiDext: Hand-Object Manipulation Synthesis via Continuous Correspondence Embeddings and Residual-Guided Diffusion
Jiajun Zhang, Yuxiang Zhang, Liang An +4
Dynamic and dexterous manipulation of objects presents a complex challenge, requiring the synchronization of hand motions with the trajectories of objects to achieve seamless and p…
Ins-HOI: Instance Aware Human-Object Interactions Recovery
Jiajun Zhang, Yuxiang Zhang, Hongwen Zhang +5
Accurately modeling detailed interactions between human/hand and object is an appealing yet challenging task. Current multi-view capture systems are only capable of reconstructing…
