New benchmark C3VDReg targets colonoscopy navigation challenges

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced C3VDReg, a new benchmark dataset and evaluation protocol designed to improve anatomical localization for colonoscopic navigation. The benchmark, derived from the Colonoscopy 3D Video Dataset (C3VD), consists of over 10,000 partial-to-partial point cloud pairs, including a held-out test set. Initial evaluations reveal that even with high geometric overlap, existing registration methods struggle to achieve reliable pose recovery, indicating a need for enhanced anatomical and contextual constraints.

    C3VDReg: A Benchmark for Local-to-Local Colonoscopic Registration toward Anatomical Localization

    arXiv:2511.00260v2 Announce Type: replace Abstract: Anatomy-aware colonoscopic navigation requires localizing partial endoscopic observations on a stable 3D reference to support coverage assessment, revisited-region awareness, and CT-guided navigation. However, rigid point cloud …
