The Scene Graph Updated When the Room Changed
DSG detects moved objects before reasoning again about their spatial relationships.
Summary
DSG detects moved objects before reasoning again about their spatial relationships.
Semantic 3D Gaussian rendering supplies dual views for change detection, updating graph nodes when an object no longer matches the remembered room. A language model then receives visual context at multiple scales to infer richer relations. Tests on DynTHOR, 3RScan and real scenes report better node construction and relationship reasoning than compared methods.
Why it matters
DSG detects moved objects before reasoning again about their spatial relationships.
Limits and context
No additional limitation was separately recorded.
Key claims
DSG detects moved objects before reasoning again about their spatial relationships.
