Towards Accurate End-Effector Localization for UMI-Style Robotic Manipulation Teaching
Junjie Zhang, Deteng Zhang, Zhisong Xu +4
Robot demonstration learning requires accurate and temporally complete end-effector localization during close-range manipulation and camera occlusion. Existing SLAM benchmarks emph…

F SLAM: Turning Feed-Forward Geometry into Persistent Factors for SLAM
Zhisong Xu, Fan Zhu, Jiawei Qian +3
Feed-forward 3D models provide strong multi-view geometric priors, while on- line simultaneous localization and mapping (SLAM) relies mainly on local mea- surements and can accumul…

FrameVGGT: Coherence-Preserving Memory for Bounded Streaming Geometry
Zhisong Xu, Takeshi Oishi
Streaming Visual Geometry Transformers such as StreamVGGT enable strong online 3D perception, but their KV-cache grows unbounded over long streams, limiting practical deployment. W…
