Voxelized 3D Gaussian Representation for Dense Visual SLAM on Embedded Vision System

A voxelized compact 3D Gaussian representation for SLAM system that reduces the number and the parameter size of Gaussian ellipsoids is proposed, and a novel residual codebook-based quantization method is proposed to further compress 3D Gaussian attributes.

DiffSAC: Diffusion-guided Sampling for Consensus-based Robust Estimation

A novel Diffusion-guided Sampling for Consensus-based Robust Estimation (DiffSAC) framework that refines the confidence for each data point, indicating whether it belongs to a good minimum set, rather than ranking the data points as in previous work, significantly reduces the need to process numerous bad sets.

Multi-Submap Implicit Neural SLAM with Local-to-Global Loop Closure for Large-Scale Scene Reconstruction

This paper presents a robust, large-scale neural SLAM system featuring a multi-submap architecture and a dual-tier loop closure mechanism, and proposes a progressive mapping strategy that dynamically allocates neural submaps to maintain high-fidelity representations without memory explosion.
