Grounded Drift Field
A learnable field defined at the reference viewpoint that absorbs cross-view inconsistencies between videos synthesized by a video model and multi-view completion. This allows the primary deformation field to learn clean and coherent dynamics, while residual inconsistencies are explained locally by the drift field rather than corrupting the learned motion.

OuroWorld proposes Inconsistency-Robust Periodic 4DGS, which contains two key components, the Fourier series deformation field and the Grounded Drift Field, to learn dynamics from imperfect supervision signals.
The Grounded Drift Field anchors a learnable drift field at the reference viewpoint to absorb cross-view inconsistency, preventing conflicting information from contaminating the entire 4D representation.
