Registration Improvements
This page will describe registration improvements made within Slicer3 to improve the usability and robustness of registration algorithms so they may be used in an interactive clinical setting.
Key Contributors
- Kitware: Casey Goodlett with consultation from Will Schroeder and Stephen Aylward
- BWH: Ron Kikinis, Dominik Meier, Andriy Fedorov
RegisterImages Algorithm
- ITK Metrics used: MattesMutualInformation
- Optimizer: OnePlusOne Evolutionary Optimizer followed by FRPR in fletcher reeves mode
- Transform Types: Rigid transform VersorRigid3DTransform, Affine transform AffineTransform, B-spline transform BSplineDeformableTransform
A user should typically one of the Pipeline methods (PipelineRigid, PipelineAffine, PipelineBspline) as these will run Initalization -> Rigid -> Affine -> Bspline to the specified level. These are run in order to convergence or maximum # of iterations. Within each pipeline step there is a two stage optimization. First the evolution optmizer is run to stochastically chose a starting location for optimization. After this the FRPR optimizer is used.
