Surface Keypoint Representation for Multi-Object and Articulated Human-Object Interaction Generation
Xiaogang Peng, Zeyu Han, Zichong Meng +4
Daily activities require humans to coordinate whole-body motion with the motion of surrounding objects. Despite recent progress in human-object interaction (HOI) generation, most e…

Rethinking Diffusion for Text-Driven Human Motion Generation: Redundant Representations, Evaluation, and Masked Autoregression
Zichong Meng, Yiming Xie, Xiaogang Peng +2
Since 2023, Vector Quantization (VQ)-based discrete generation methods have rapidly dominated human motion generation, primarily surpassing diffusion-based continuous generation me…

Absolute Coordinates Make Motion Generation Easy
Zichong Meng, Zeyu Han, Xiaogang Peng +2
State-of-the-art text-to-motion generation models rely on the kinematic-aware, local-relative motion representation popularized by HumanML3D, which encodes motion relative to the p…
