3DGS${}^2$-TR: Scalable Second-Order Trust-Region Method for 3D Gaussian Splatting

Roger Hsiao, Yuchen Fang, Xiangru Huang +6

We propose 3DGS${}^2$-TR,a second-order optimizer for accelerating the scene training problem in 3D Gaussian Splatting (3DGS). Unlike existing second-order approaches that rely on ex…
