Latest 50 papers on gaussian splatting: Oct. 20, 2025
Gaussian Splatting (GS) has rapidly become a cornerstone in 3D reconstruction and neural rendering, captivating researchers and developers alike with its impressive photorealism and real-time performance. This dynamic field is continually evolving, pushing the boundaries of what’s possible in capturing, rendering, and interacting with 3D environments. This post dives into a collection of recent research papers, showcasing how GS is being refined, optimized, and extended to tackle some of the most pressing challenges in AI/ML.
The Big Idea(s) & Core Innovations
Recent research in Gaussian Splatting highlights a strong push towards greater efficiency, enhanced geometric fidelity, and expanded applications across diverse domains. A recurring theme is the integration of GS with other powerful AI/ML techniques, such as diffusion models and vision-language models, to unlock new capabilities.
One significant area of innovation is dynamic scene reconstruction and avatar generation. For instance, Human-VDM: Learning Single-Image 3D Human Gaussian Splatting from Video Diffusion Models from Sun Yat-Sen University and Carnegie Mellon University pioneers high-fidelity 3D human generation from single images by leveraging video diffusion models for view consistency. Similarly, Meta researchers in their paper Capture, Canonicalize, Splat: Zero-Shot 3D Gaussian Avatars from Unstructured Phone Images introduce a zero-shot pipeline for hyper-realistic 3D avatars from unstructured phone images, using a generative canonicalization module to preserve identity. Further enhancing this, Virtually Being: Customizing Camera-Controllable Video Diffusion Models with Multi-View Performance Captures by Eyeline Labs and Stanford University introduces a novel framework for camera-controllable video generation, integrating multi-view performance captures and 4D Gaussian Splatting.
Addressing efficiency and quality in challenging scenarios is another major focus. BSGS: Bi-stage 3D Gaussian Splatting for Camera Motion Deblurring from Nanjing University of Aeronautics and Astronautics tackles motion blur, leveraging a bi-stage optimization to reconstruct high-quality scenes. For dynamic urban scenes, PAGS: Priority-Adaptive Gaussian Splatting for Dynamic Driving Scenes by Harbin Institute of Technology and Li Auto introduces semantic priorities to accelerate rendering of safety-critical elements while maintaining fidelity. In the realm of compression, P-4DGS: Predictive 4D Gaussian Splatting with 90× Compression from the University of Science and Technology of China achieves remarkable 90x compression rates for 4D scenes, drawing inspiration from video coding techniques. On the hardware front, TC-GS: A Faster Gaussian Splatting Module Utilizing Tensor Cores by University of Technology, Shanghai, et al., demonstrates significant speedups in alpha-blending by leveraging Tensor Cores, expanding their utility beyond traditional GEMM operations.
Beyond visual fidelity, several papers integrate geometric cues and multimodal rendering. UniGS: Unified Geometry-Aware Gaussian Splatting for Multimodal Rendering from HKUST (GZ) introduces a framework for jointly predicting RGB, depth, normal, and semantic maps. For robust surface reconstruction from monocular images, MonoGSDF: Exploring Monocular Geometric Cues for Gaussian Splatting-Guided Implicit Surface Reconstruction by Technical University of Munich et al., combines Gaussian primitives with neural Signed Distance Fields (SDF). This emphasis on geometry is further echoed in VA-GS: Enhancing the Geometric Representation of Gaussian Splatting via View Alignment from Southwest Jiaotong University, which improves geometric accuracy through edge-aware and visibility-aware supervision.
