Leveraging a conditional generative model, our model uncovers and learns shape symmetry and part interchangeability. As a result, it generalizes across categories and datasets, achieving SoTA performance across multiple benchmarks.

RPF directly generates the assembled-state point clouds from unposed 3D parts, enabling pose estimation entirely from shape, without correspondence learning, pose regression, or symmetry labels.

Point maps have become a powerful representation for image-based 3D reconstruction. What if we could push point maps even further to tackle 3D registration and assembly?
Introducing Rectified Point Flow (RPF), a generic formulation for point cloud pose estimation.

🚨 SLAM struggling in dynamic environments? We've been there.

WildGS-SLAM at #CVPR2025, our new monocular RGB SLAM system, tackles dynamic scenes with uncertainty-aware tracking and mapping, resulting to more robust tracking, cleaner maps, and high-quality view synthesis. ⬇️
