Researchers have introduced HiSC, a novel framework designed to enhance the efficiency of 3D vision-language models (3D VLMs). This training-free approach addresses the significant token redundancy in 3D scenes by organizing tokens into spatially grounded clusters. HiSC employs a spatial graph-based merging strategy to consolidate similar redundant tokens before inference and a hierarchical compression method during inference to preserve object completeness and fine-grained details. Experiments demonstrate that HiSC can achieve over 90% token reduction with minimal performance degradation on various 3D reasoning benchmarks. AI
IMPACT HiSC's approach to token compression could significantly reduce computational costs for 3D vision-language models, enabling more efficient spatial reasoning.
