How VGGT Understands Co-Visibility
zhenjun_zhao · x · 2026-07-14
Titled "What VGGT Knows About Overlap: Probing Geometric Foundation Models for Co-Visibility", this work analyzes how geometric foundation models perceive image overlap and co-visibility.
The tl;dr from the post:
- Early layers lean towards forming 3D-aware scene representations;
- Late layers are more focused on learning co-visibility;
- The paper also proposes a VGGT + MoE head approach.
Overall, it probes what geometric foundation models actually "know" from a representation perspective.
