FS-I2P:A Hierarchical Focus-Sweep Registration Network with Dynamically Allocated Depth

Baoqun Yin, Bohao Liao, Tianzhu Zhang, Xiaotian Yin, Xujing Tao, Yujia Chen, Zhixin Cheng

A focus-sweep interaction module with dynamic depth allocation improves cross-modal image-to-point cloud registration by cutting attention drift.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Extensive experiments and ablations on two benchmarks, RGB-D Scenes V2 and 7-Scenes, demonstrate that our approach achieves state-of-the-art performance.

C2weakest assumption

The Hierarchical Focus-Sweep Interaction Module and Dynamic Layer Allocation Strategy actually reduce attention drift and intra-scale inconsistencies enough to produce the claimed registration gains.

C3one line summary

FS-I2P uses a focus-sweep paradigm and dynamic layer allocation in an SSM framework to achieve state-of-the-art image-to-point cloud registration on RGB-D Scenes V2 and 7-Scenes benchmarks.
