Explicit Memory through Online 3D Gaussian Splatting Improves Class-Agnostic Video Segmentation

ICRA 2026poster

Remembering where object segments were predicted in the past is useful for improving the accuracy and consistency of class-agnostic video segmentation algorithms. Existing video segmentation algorithms typically use either no object-level memory (e.g. FastSAM) or they use implicit memories in the fo…

POp-GS: Next Best View in 3D-Gaussian Splatting with P-Optimality

CVPR 2025poster

In this paper, we present a novel algorithm for quantifying uncertainty and information gained within 3D Gaussian Splatting (3D-GS) through P-Optimality. While 3D-GS has proven to be a useful world model with high-quality rasterizations, it does not natively quantify uncertainty or information, posi…
