Spatially Constrained 3D Scene Graphs for Scene-Grounded Subtask Generation

3D scene graphs connect spatial perception with high-level language reasoning, but unverified false-positive groundings can impair downstream subtask generation. We propose a feed-forward, spatially constrained framework that grounds task-relevant objects and generates position-aware subtasks without an iterative task–...

M2Depth: Unifying Monocular Depth Foundation Priors with Multi-View Stereo

This work proposes a novel framework that overcomes this limitation by tightly coupling a DFM with a cascade MVS pipeline through a bidirectional mutual refinement strategy, and introduces a prior-guided cost volume refinement mechanism that effectively integrates multi-view and monocular information via attention-base...
