Extreme Views: 3DGS Filter for Novel View Synthesis from Out‑of‑Distribution Camera Poses

The paper “Extreme Views: 3DGS Filter for Novel View Synthesis from Out‑of‑Distribution Camera Poses” by Damian Bowness and Charalambos Poullis will appear in the 20th International Symposium on Visual Computing (ISVC), 2025. TL;DR: A plug‑in, real‑time filter for 3D Gaussian Splatting that performs a rotation‑

Multi-view Gradient Consistency for SVBRDF Estimation of Complex Scenes under Natural Illumination

Some results from the technique detailed in the paper "Multi-view Gradient Consistency for SVBRDF Estimation of Complex Scenes under Natural Illumination" by Alen Joy and Charalambos Poullis. TL;DR: The diffuse component is independent of the viewer's direction, therefore, when solving for BRDFs, the gradients from
