GeoWeaver: Accurate Long-Sequence 3D Reconstruction via Hierarchical Geometric Assembly

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: Unified 4D Scene Reconstruction from a Single Query

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.
