CSCPR: Cross-Source-Context Indoor RGB-D Place Recognition

RA-L 2025

We extend our previous work, PoCo (Liang et al. 2024), and present a new algorithm, Cross-Source-Context Place Recognition (CSCPR), for RGB-D indoor place recognition that integrates global retrieval and reranking into an end-to-end model and keeps the consistency of using Context-of-Clusters (CoCs)

Modeling Uncertainty in 3D Gaussian Splatting Through Continuous Semantic Splatting

ICRA 2025

In this paper, we present a novel algorithm for probabilistically updating and rasterizing semantic maps within 3D Gaussian Splatting (3D-GS). Although previous methods have introduced algorithms which learn to rasterize features in 3D-GS for enhanced scene understanding, 3D-GS can fail without warn

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…

Correspondence-Free SE(3) Point Cloud Registration in RKHS via Unsupervised Equivariant Learning

ECCV 2024poster

"This paper introduces a robust unsupervised SE(3) point cloud registration method that operates without requiring point correspondences. The method frames point clouds as functions in a reproducing kernel Hilbert space (RKHS), leveraging SE(3)-equivariant features for direct feature space registrat…

PoCo: Point Context Cluster for RGBD Indoor Place Recognition

IROS 2024

We present a novel end-to-end algorithm (PoCo) for the indoor RGB-D place recognition task, aimed at identifying the most likely match for a given query frame within a reference database. The task presents inherent challenges attributed to the constrained field of view and limited range of perceptio
