SpaTime: Streaming Vision-Language Models for Spatio-temporal Reasoning
Hairong Yin, Huangying Zhan, Shin-Fang Chng +2
Embodied agents must reason about 3D space while the video is still arriving, answering questions as soon as they have observed enough of the scene. VLMs that incorporate 3D geomet…
StereoGaussians: Feed-Forward 3D Gaussian Splatting from Stereo Images
Boyuan Tian, Huangying Zhan, Zhan Li +4
Feed-forward 3D Gaussian Splatting (3DGS) enables reconstruction without per- scene optimisation, but practical stereo-camera applications require nearby-view extrapolation beyond…
4DGS-Fixer: Generative Sparse-View 4D Gaussian Splatting with Iterative Refinement Guided by Video Diffusion Priors
Haitao Huang, Shenghao Zhao, Boyuan Tian +7
This paper addresses the challenges of dynamic scene synthesis from sparse-view videos. Existing methods employ geometric priors, adaptive optimization, or density-control strategi…
FluSplat: Sparse-View 3D Editing without Test-Time Optimization
Haitao Huang, Shin-Fang Chng, Huangying Zhan +2
Recent advances in text-guided image editing and 3D Gaussian Splatting (3DGS) have enabled high-quality 3D scene manipulation. However, existing pipelines rely on iterative edit-an…
FAST3DIS: Feed-forward Anchored Scene Transformer for 3D Instance Segmentation
Changyang Li, Xueqing Huang, Shin-Fang Chng +3
While recent feed-forward 3D reconstruction models provide a strong geometric foundation for scene understanding, extending them to 3D instance segmentation typically relies on a d…
G3Splat: Geometrically Consistent Generalizable Gaussian Splatting
Mehdi Hosseinzadeh, Shin-Fang Chng, Yi Xu +3
3D Gaussians have become a powerful scene representation for real-time splatting and high-quality novel-view synthesis. This has motivated generalizable splatting -- methods that a…
