Detailed Description

An interface method to the modular ITKv4 registration framework.

This interface method class encapsulates typical registration usage by incorporating all the necessary elements for performing a simple image registration between two images. This method also allows for multistage registration whereby each stage is characterized by possibly different transforms and different image metrics. For example, many users will want to perform a linear registration followed by deformable registration where both stages are performed in multiple levels. Each level can be characterized by:

the resolution of the virtual domain image (see below)
smoothing of the fixed and moving images

Multiple stages are handled by linking multiple instantiations of this class where the output transform is added to the optional composite transform input.

◆ GetFixedInitialTransform()

Transform itk::simple::ImageRegistrationMethod::GetFixedInitialTransform ( ) const

inline

Set transform mapping to the fixed domain.

This transform is used to map from the virtual domain to the fixed image domain.

By default this transform is an identity, and not used.

See also: itk::ImageRegistrationMethodv4::SetFixedInitialTransform

Definition at line 198 of file sitkImageRegistrationMethod.h.

◆ GetInitialTransform()

Transform itk::simple::ImageRegistrationMethod::GetInitialTransform ( )

inline

Set the initial transform and parameters to optimize.

This transform is applied before the MovingInitialTransform, to map from the virtual image domain to the moving image domain.

If the inPlace flag is explicitly false, then the ITK registration will internally make a copy, and the transform will not be accessible during registration. Otherwise, the accessible InitialTransform value will be the same object used during registration, and will have a modified value upon completion.

◆ GetInitialTransformInPlace()

bool itk::simple::ImageRegistrationMethod::GetInitialTransformInPlace ( ) const

inline

Set the initial transform and parameters to optimize.

This transform is applied before the MovingInitialTransform, to map from the virtual image domain to the moving image domain.

If the inPlace flag is explicitly false, then the ITK registration will internally make a copy, and the transform will not be accessible during registration. Otherwise, the accessible InitialTransform value will be the same object used during registration, and will have a modified value upon completion.

◆ GetMetricNumberOfValidPoints()

uint64_t itk::simple::ImageRegistrationMethod::GetMetricNumberOfValidPoints ( ) const

Current number of points used of metric evaluation

This is a active measurement connected to the registration processes during registration. This number is number of point in the virtual domain which overlap the fixed image and the moving image. It is valid for sparse or dense sampling. After execution of registration this will contain the last value.

◆ GetMetricSamplingPercentagePerLevel()

◆ GetMovingInitialTransform()

Transform itk::simple::ImageRegistrationMethod::GetMovingInitialTransform ( ) const

inline

Set a fixed transform component towards moving domain.

The InitialTransform is added to this transform to form the composite transform which maps from the virtual domain to the moving image's domain. The parameters of this transform are not optimized. This is an advanced option used when the output transformed with be composed into a composite transform.

By default this transform is an identity, and not used.
