Lifting Unlabeled Internet-level Data for 3D Scene Understanding

Yixin Chen, Yaowei Zhang, Huangyue Yu +9

Annotated 3D scene data is scarce and expensive to acquire, while abundant unlabeled videos are readily available on the internet. In this paper, we demonstrate that carefully desi…

Trace3D: Consistent Segmentation Lifting via Gaussian Instance Tracing

Hongyu Shen, Junfeng Ni, Yixin Chen +3

We address the challenge of lifting 2D visual segmentation to 3D in Gaussian Splatting. Existing methods often suffer from inconsistent 2D masks across viewpoints and produce noisy…
