Latest 50 papers on gaussian splatting: Oct. 6, 2025

Gaussian Splatting (GS) has rapidly emerged as a foundational technology in 3D reconstruction and neural rendering, offering an unparalleled balance of visual fidelity and rendering speed. What began as a powerful method for novel view synthesis is now transforming into a versatile toolkit for a myriad of complex challenges in computer vision, robotics, and even medical imaging. Recent research highlights a burgeoning field, pushing the boundaries of what’s possible, from generating dynamic, relightable scenes to robustly perceiving environments through smoke and reflections.

The Big Idea(s) & Core Innovations

The core innovation across many of these papers lies in extending 3DGS beyond static scene representation, tackling challenges like dynamic content, semantic understanding, and robust reconstruction under adverse conditions. Researchers are creatively adapting Gaussian Splatting to solve real-world problems that demand both speed and accuracy.

Take, for instance, the realm of dynamic scene generation. HDR Dynamic Novel View Synthesis (HDR DNVS), introduced by Kaixuan Zhang et al. from Nanjing University of Science and Technology, leverages a Gaussian Splatting-based framework, HDR-4DGS, with a dynamic tone-mapping module to generate photorealistic high dynamic range (HDR) images from low dynamic range inputs in dynamic scenes. Similarly, the 4D Driving Scene Generation With Stereo Forcing paper by Hao Lu et al. from Hong Kong University of Science and Technology introduces PhiGenesis, a unified framework that generates temporally consistent and geometrically accurate 4D driving scenes, utilizing a technique called Stereo Forcing to enhance geometric consistency.

In the interactive domain, GaussEdit: Adaptive 3D Scene Editing with Text and Image Prompts by Zhenyu Shu et al. from NingboTech University, empowers users to manipulate 3D scenes with unprecedented precision using intuitive text and image prompts. This is complemented by 4DGS-Craft: Consistent and Interactive 4D Gaussian Splatting Editing by Lei Liu et al. from The University of Hong Kong, which extends editing capabilities to 4D GS representations, ensuring consistency across views and time through LLM integration.

Robustness and realism are also key themes. Seeing Through Reflections by Zijing Guo et al. from Shanghai Jiao Tong University introduces ReflectiveGS, which uses mirror reflections as complementary viewpoints to improve 3D scene reconstruction. For challenging environments, SmokeSeer: 3D Gaussian Splatting for Smoke Removal and Scene Reconstruction by Neham Jain et al. from Carnegie Mellon University, combines RGB and thermal imaging with 3DGS to literally see and reconstruct scenes through dense smoke.

Further pushing the fidelity envelope, Spec-Gloss Surfels and Normal-Diffuse Priors for Relightable Glossy Objects by Georgios Kouros et al. from KU Leuven, enhances the reconstruction and relighting of glossy objects by integrating microfacet BRDF with specular-glossiness parameterization into 2D Gaussian Splatting. Meanwhile, MPMAvatar: Learning 3D Gaussian Avatars with Accurate and Robust Physics-Based Dynamics from KAIST researchers Changmin Lee et al. enables realistic 3D human avatars with physically accurate garment animations using a tailored Material Point Method (MPM)-based simulator.
