DynaConTalk: Wavelet-Constrained Diffusion for Long-Form and Controllable Holistic Co-Speech 3D Motion
Yifei Zhu, Yangyang Cai, Mingyi Shi +4
Holistic co-speech animation is prone to averaging in both motion representation and speech conditioning. In coordinate-space diffusion, slow body posture, mid-frequency gesture st…
MoRAE: Flow-Friendly Self-Supervised Latents for Text-to-Motion Generation
Yifei Zhu, Mingyi Shi, Yangyang Cai +3
Text-to-motion generation must produce motions that are semantically correct, temporally coherent, and physically plausible. A natural approach is to first project motion data into…
AirGS: Real-Time 4D Gaussian Streaming for Free-Viewpoint Video Experiences
Zhe Wang, Jinghang Li, Yifei Zhu
Free-viewpoint video (FVV) enables immersive viewing experiences by allowing users to view scenes from arbitrary perspectives. As a prominent reconstruction technique for FVV gener…
NeRFlex: Resource-aware Real-time High-quality Rendering of Complex Scenes on Mobile Devices
Zhe Wang, Yifei Zhu
Neural Radiance Fields (NeRF) is a cutting-edge neural network-based technique for novel view synthesis in 3D reconstruction. However, its significant computational demands pose ch…
