UVG-GS: Human-Centric Gaussian Splats Dataset for Visual Volumetric Compression

Abstract

Gaussian splats (GS) enable high-quality 3D reconstruction but also pose significant challenges for efficient compression. This paper introduces UVG-GS, a human-centric dataset designed for compression-oriented evaluation of GS. The dataset comprises 11 human-centric sequences that extend our existing point cloud and mesh datasets by incorporating GS representations. These representations are obtained through depth-guided manual segmentation and third-party standard tools, such as COLMAP and gsplat. Our dataset also provides RGB-D data, camera parameters, segmentation masks, and the complete GS processing pipeline to support reproducible research on GS generation and compression.
