MoGeFlow: Flowing Through Motion Codebook Geometry for Text-to-Motion Generation

Pengcheng Fang, Tengjiao Sun, Xiaoyu Zhan +2

Vector-quantized motion tokenizers provide a compact discrete interface for text-to-motion generation, but most motion-code priors treat code indices as unordered categorical label…

KV-Control: Parameter-Efficient K/V Injection for Trajectory-Controlled Text-to-Motion

Tengjiao Sun, Pengcheng Fang, Xiaoyu Zhan +4

Text-conditioned 3D human motion models now synthesize plausible motions from prompts, but practical animation and embodied-agent workflows rarely stop at text: a character may nee…

MotionDuet: Dual-Conditioned 3D Human Motion Generation with Video-Regularized Text Learning

Yi-Yang Zhang, Tengjiao Sun, Pengcheng Fang +4

3D Human motion generation is pivotal across film, animation, gaming, and embodied intelligence. Traditional 3D motion synthesis relies on costly motion capture, while recent work…

AnchorRoute: Human Motion Synthesis with Interval-Routed Sparse Contro

Pengcheng Fang, Tengjiao Sun, Dongjie Fu +4

Sparse anchors provide a compact interface for human motion authoring: users specify a few root positions, planar trajectory samples, or body-point targets, while the system synthe…

UMo: Unified Sparse Motion Modeling for Real-Time Co-Speech Avatars

Xiaoyu Zhan, Xinyu Fu, Chenghao Yang +9

Speech-driven gestures and facial animations are fundamental to expressive digital avatars in games, virtual production, and interactive media. However, existing methods are either…

CHASM: Cross-frequency Harmonized Axis-Separable Mixing for Spectral Token Operators

Pengcheng Fang, Hongli Chen, Yuxia Chen +3

Spectral token mixers based on Fourier transforms provide an efficient way to model global interactions in visual feature maps. Existing designs often either apply filter-wise spec…
