GHOST: Geometry-Hierarchical Online Streaming Token Eviction for Efficient 3D Reconstruction arXiv:2605.15852v2 Announce Type: replace Abstract: Streaming 3D reconstruction from long monocular video sequences requires maintaining a key-value (KV) cache that grows linearly with sequence length, creating a severe memory bottleneck. Existing approaches either truncate the cache to a fixed set of anchor frames, leading to reconstruction quality degradation, or rely on attention-score heuristics tha
