A normal-guided depth propagation approach is introduced, which can extend depth information from high-confidence regions to constrain the depth in low-confidence areas and an abnormal depth edge-aware regularization is proposed to address depth discontinuities caused by the discreteness of Gaussians.
This paper proposes a novel yet simple partitioning method to efficiently and faithfully reconstruct large-scale scene surfaces and proposes a strategy to detect and repair missing regions in the initial point cloud caused by sparse viewpoints or insufficient textures, thereby further improving the geometric quality.
GeoWeaver, a unified framework comprising a Geometric Prior Model (GPM) and Test-Time Adaptation (TTA) and a robust CDF-style objective jointly optimizes weighted 2D reprojection and 3D consistency residuals, is presented.

UniQuery4R is presented, a query-conditioned framework that encodes a multi-frame clip once and selects the source view, target view, and continuous source-image coordinate only at decoding time via source-to-target cross-attention, and introduces a direction-magnitude parameterization of scene flow with separate supervision for moving and static points.
