ARMFlow: AutoRegressive MeanFlow for Online 3D Human Reaction Generation

CVPR 2026

3D human reaction generation faces three main challenges: (1) high motion fidelity, (2) real-time inference, and (3) autoregressive adaptability for online scenarios. Existing methods fail to meet all three simultaneously. We propose ARMFlow, a MeanFlow-based autoregressive framework that models tem

Disentangled Hierarchical VAE for 3D Human-Human Interaction Generation

ICLR 2026poster

Generating realistic 3D Human-Human Interaction (HHI) requires coherent modeling of the physical plausibility of the agents and their interaction semantics. Existing methods compress all motion information into a single latent representation, limiting their ability to capture fine-grained actions an…

Auto-Regressive Diffusion for Generating 3D Human-Object Interactions

AAAI 2025technical

Text-driven Human-Object Interaction (Text-to-HOI) generation is an emerging field with applications in animation, video games, virtual reality, and robotics. A key challenge in HOI generation is maintaining interaction consistency in long sequences. Existing Text-to-Motion-based approaches, such as…

MonoDiff9D: Monocular Category-Level 9D Object Pose Estimation via Diffusion Model

ICRA 2025

Object pose estimation is a core means for robots to understand and interact with their environment. For this task, monocular category-level methods are attractive as they require only a single RGB camera. However, current methods rely on shape priors or CAD models of the intra-class known objects.
