Enhancing Image Registration Framework

Goals

  • Review v4 registration plans and progress.
  • Catalog target use cases.
  • Discuss design changes in core itk to support these enhancements.
  • Wishlist items beyond standard use cases, e.g. projective transform (itkPerspective3DTransform).

Discussion Items

  • Separate sampling (interpolation strategy) and metric computation
  • Separate computation of derivative components via chain rule.
  • Enable registration of generalized data-types.
  • Multiple metrics and/or multiple optimizers?
  • Add feature based registration techniques (SIFT (patented?), SURF, etc)
