EmbodMocap: In-the-Wild 4D Human-Scene Reconstruction for Embodied Agents

CVPR 2026

Human behaviors in the real world naturally encode rich, long-term contextual information that can be leveraged to train embodied agents for perception, understanding, and acting.However, existing capture systems typically rely on costly studio setups and wearable devices, limiting the large-scale c

Gloria: Consistent Character Video Generation via Content Anchors

CVPR 2026

Digital characters are central to modern media, yet generating character videos with long-duration, consistent multi-view appearance and expressive identity remains challenging. Existing approaches either provide insufficient context to preserve identity or leverage non-character-centric information

Mocap-2-to-3: Multi-view Lifting for Monocular Motion Recovery with 2D Pretraining

CVPR 2026

Human motion recovery for real-world interaction demands both precise action details and metric-scale trajectories. Recovering absolute human pose from monocular input presents a viable solution, but faces two main challenges: (1) models' reliance on 3D training data from constrained environments li

MotionStreamer: Streaming Motion Generation via Diffusion-based Autoregressive Model in Causal Latent Space

ICCV 2025poster

This paper addresses the challenge of text-conditioned streaming motion generation, which requires us to predict the next-step human pose based on variable-length historical motions and incoming texts. Existing methods struggle to achieve streaming motion generation, e.g., diffusion models are const…

Ready-to-React: Online Reaction Policy for Two-Character Interaction Generation

ICLR 2025poster

This paper addresses the task of generating two-character online interactions. Previously, two main settings existed for two-character interaction generation: (1) generating one's motions based on the counterpart's complete motion sequence, and (2) jointly generating two-character motions based on s…

Generating Human Motion in 3D Scenes from Text Descriptions

CVPR 2024poster

Generating human motions from textual descriptions has gained growing research interest due to its wide range of applications. However only a few works consider human-scene interactions together with text conditions which is crucial for visual and physical realism. This paper focuses on the task of…

A Joint Modeling of Vision-Language-Action for Target-oriented Grasping in Clutter

ICRA 2023poster

We focus on the task of language-conditioned grasping in clutter, in which a robot is supposed to grasp the target object based on a language instruction. Previous works separately conduct visual grounding to localize the target object, and generate a grasp for that object. However, these works requ…

Hierarchical Generation of Human-Object Interactions with Diffusion Probabilistic Models

ICCV 2023poster

This paper presents a novel approach to generating the 3D motion of a human interacting with a target object, with a focus on solving the challenge of synthesizing long-range and diverse motions, which could not be fulfilled by existing auto-regressive models or path planning-based methods. We propo…
