• Only What Was Seen: Observation-Gram Compaction of View-Dependent Appearance in 3D Gaussian Splatting

  Krzysztof Pietroszek · 25. September 2026

  Most of the memory of a 3D Gaussian Splatting model holds spherical-harmonic colour coefficients, yet each Gaussian is seen only from the narrow cone of directions of the training cameras. We turn this into a distortion metric that other compressors can adopt: a per-Gaussian observation Gram matrix,…

• PlenoCI: Plenoptic CharacterIstics for View Dependence Aware Change Classification

  Jason Lai, Chamuditha Jayanga Galappaththige, Niko Suenderhauf, Dimity Miller, Donald G. Dansereau · 25. September 2026

Independently optimized reconstructions converge to different primitive configurations, even in unchanged reg…

• ADATEX4D: adaptive texture capacity allocation for 4D gaussian splatting

  De Jiang, Peiqiang Wang, Kehong Yuan, Shaohua Ma · 25. September 2026

  Textured Gaussians improve local appearance capacity, but assigning the same texture resolution to every primitive wastes storage on low-detail or weakly visible regions. We introduce AdaTex4D, an adaptive texture-capacity module for deformation-based 4D Gaussian Splatting. Each Gaussian carries pac…
