VCURF: Virtual Camera-based Uncertainty of Radiance Fields
Liyan Chen, Nathaniel Burgdorfer, Philippos Mordohai
Radiance fields, implemented with either implicit (NeRF) or explicit (Gaussian Splatting) representations, are advancing the state of the art in novel view synthesis at a rapid pac…

ActiveGAMER: Active GAussian Mapping through Efficient Rendering
Liyan Chen, Huangying Zhan, Kevin Chen +4
We introduce ActiveGAMER, an active mapping system that utilizes 3D Gaussian Splatting (3DGS) to achieve high-quality, real-time scene mapping and exploration. Unlike traditional N…

Flash3D: Super-scaling Point Transformers through Joint Hardware-Geometry Locality
Liyan Chen, Gregory P. Meyer, Zaiwei Zhang +2
Recent efforts recognize the power of scale in 3D learning (e.g. PTv3) and attention mechanisms (e.g. FlashAttention). However, current point cloud backbones fail to holistically u…
