UDGS-SLAM: UniDepth Assisted Gaussian Splatting for Monocular SLAM

Array
Recent advancements in monocular neural depth estimation, particularly those achieved by the UniDepth network, have prompted the investigation of integrating UniDepth within a Gaussian splatting framework for monocular SLAM. This study presents UDGS-SLAM,

Robust Gaussian Splatting

In this paper, we address common error sources for 3D Gaussian Splatting (3DGS) including blur, imperfect camera poses, and color inconsistencies, with the goal of improving its robustness for practical applications like reconstructions from handheld phone captures.

Visual Simulation of Flow [PDF]

, 2010
We have adopted a numerical method from computational fluid dynamics, the Lattice Boltzmann Method (LBM), for real-time simulation and visualization of flow and amorphous phenomena, such as clouds, smoke, fire, haze, dust, radioactive plumes, and air ...

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Effect of Ce/La Substitution on Optical Transparency and Ionic Conductivity of Sodium Silicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We investigate sodium silicate glasses modified with Ce2O3 and La2O3 to explore the interplay between optical absorption, structure, and macroscopic properties. Ce doping drives a pronounced red‐shift of the absorption edge into the visible region (> 500 nm), arising from O2− →$ \to $ Ce4+ charge‐transfer and intervalence transitions ...

Gaussian Splatting: 3D Reconstruction and Novel View Synthesis: A Review

IEEE Access
Image-based 3D reconstruction is a challenging task that involves inferring the 3D shape of an object or scene from a set of input images. Learning-based methods have gained attention for their ability to directly estimate 3D shapes.

DreamGaussian4D: Generative 4D Gaussian Splatting

, 2023
4D content generation has achieved remarkable progress recently. However, existing methods suffer from long optimization times, a lack of motion controllability, and a low quality of details. In this paper, we introduce DreamGaussian4D (DG4D), an efficient 4D generation framework that builds on Gaussian Splatting (GS). Our key insight is that combining
