RiGS: Rigid-aware 4D Gaussian Splatting from a Single Monocular Video

Researchers introduced RiGS, a rigid-aware 4D Gaussian Splatting method for reconstructing dynamic scenes from monocular video.

RiGS separates scenes into static, rigid, and transient Gaussian primitives, using object masks and scene flow guidance to capture motion over time.

The approach is designed to handle both slow structural changes and fast deformations more consistently than prior methods.

It achieved state-of-the-art results on novel view synthesis benchmarks, improving real-world dynamic scene reconstruction and 3D understanding.
