GeoGR: Spatial-Semantic Token Compression and Group Routing for Efficient 3D VLMs
Multi-view representations enable pretrained image and video vision-language models to understand 3D scenes, but their long visual token sequences make inference costly. Redundancy arises both from repeated observations of the same scene regions across views and from processing all visual tokens at every LLM layer, reg...
