SmartMage targets adaptive modality use in 3D scene understanding
The proposed MLLM routes visual and geometric inputs based on query relevance.
Why it matters
The work addresses a common limitation in multimodal AI systems: fixed modality combinations can add noise and waste computation when a query only needs certain inputs. Dynamic modality routing could improve efficiency and reasoning quality for embodied AI and 3D perception systems.
The key points
- 1.SmartMage dynamically selects modalities for each 3D scene query.
- 2.SMART routes inputs using semantics, alignment and modality quality.
- 3.Authors report state-of-the-art results across five benchmarks.
A new paper proposes SmartMage, a multimodal large language model for semantic-aware 3D scene understanding. The system uses a SMART module to select task-relevant modalities based on semantic priors, text-modality alignment and modality quality, plus a MAGE module to guide expert activation with modality priors. The authors report state-of-the-art performance across five 3D scene understanding benchmarks.
