LagrangeGS: Non-Conservative Lagrangian System on Dynamic 3D Gaussian Splatting

Shogo Sato, Takuhiro Kaneko, Shoichiro Takeda +4

Dynamic 3D Gaussian Splatting (3DGS) achieves photorealistic reconstruction of time-varying scenes, and recent physics-aware extensions improve extrapolation by explicitly predicti…

Objective, Absolute and Hue-aware Metrics for Intrinsic Image Decomposition on Real-World Scenes: A Proof of Concept

Shogo Sato, Masaru Tsuchida, Mariko Yamaguchi +4

Intrinsic image decomposition (IID) is the task of separating an image into albedo and shade. In real-world scenes, it is difficult to quantitatively assess IID quality due to the…

Unsupervised Intrinsic Image Decomposition with LiDAR Intensity Enhanced Training

Shogo Sato, Takuhiro Kaneko, Kazuhiko Murasaki +3

Unsupervised intrinsic image decomposition (IID) is the process of separating a natural image into albedo and shade without these ground truths. A recent model employing light dete…
