scikit-surgeryutils is a python project containing small demo apps, and small command apps, the sort of thing that probably doesn’t warrant its own project.

  • - shows a millisecond timer and video image to measure lag.
  • - extracts charuco points and annotates video image with each id detected.
  • - renders a VTK model, using OpenCV camera intrinsics.

scikit-surgeryutils is part of the SNAPPY software project, developed at the Wellcome EPSRC Centre for Interventional and Surgical Sciences, part of University College London (UCL).
