    HyKey integrates hyperspectral imaging with 3D reconstruction to enhance minimally invasive surgical procedures.

  • 2

    The system employs a 3D-2D CNN to extract spectral-spatial features, improving keypoint detection and descriptor accuracy.

  • 3

    Geometry-aware supervision during training enhances relative pose recovery, addressing challenges in surgical environments.

  • 4

    HyKey is validated using dual-modality datasets from robotic ex vivo and in vivo laparoscopic procedures.

  • 5

    Comprehensive benchmarking demonstrates HyKey's superiority in homography metrics compared to traditional RGB and HSI methods.
