elastix::SimilarityTransformElastix< TElastix > Class Template Reference

#include <elxSimilarityTransform.h>

Detailed Description

template<typename TElastix>
class elastix::SimilarityTransformElastix< TElastix >

A transform based on the itk SimilarityTransforms.

This transform is a rigid body transformation, with an isotropic scaling. In 2D, the order of parameters is:
[scale, rotation angle, translationx, translationy]
In 3D, the order of parameters is:
[versor1 versor2 versor3 translationx translationy translationz scale]
Make sure, when specifying the Scales manually that you keep in mind this order!

The parameters used in this class are:

Parameters

Transform: Select this transform as follows:
(Transform "SimilarityTransform")

Scales: the scale factor between the rotations, translations, and the isotropic scaling, used in the optimizer.
example: (Scales 100000.0 60000.0 ... 80000.0)
With this transform, the number of arguments should be equal to the number of parameters: for each parameter its scale factor. If this parameter option is not used, by default the rotations are scaled by a factor of 100000.0 and the scale by a factor 10000.0. These are rather arbitrary values. See also the AutomaticScalesEstimation parameter. See also the comment in the documentation of SimilarityTransformElastix about the order of the parameters in 2D and 3D.

AutomaticScalesEstimation: if this parameter is set to "true" the Scales parameter is ignored and the scales are determined automatically.
example: ( AutomaticScalesEstimation "true" )
Default: "false" (for backwards compatibility). Recommended: "true".

CenterOfRotation: an index around which the image is rotated.
example: (CenterOfRotation 128 128 90)
By default the CenterOfRotation is set to the geometric center of the image.

AutomaticTransformInitialization: whether or not the initial translation between images should be estimated as the distance between their centers.
example: (AutomaticTransformInitialization "true")
By default "false" is assumed. So, no initial translation.

AutomaticTransformInitializationMethod: how to initialize this transform. Should be one of {GeometricalCenter, CenterOfGravity}.
example: (AutomaticTransformInitializationMethod "CenterOfGravity")
By default "GeometricalCenter" is assumed.

The transform parameters necessary for transformix, additionally defined by this class, are:

Transform Parameters

CenterOfRotationPoint: stores the center of rotation, expressed in world coordinates.
example: (CenterOfRotationPoint 10.555 6.666 12.345)

The destructor.

Member Function Documentation

BeforeRegistration()

template<typename TElastix>

void elastix::SimilarityTransformElastix< TElastix >::BeforeRegistration ( )

overridevirtual

Execute stuff before the actual registration:

• Call InitializeTransform
• Set the scales.

Reimplemented from elastix::BaseComponent.

CreateDerivedTransformParameterMap()

template<typename TElastix>

ParameterMapType elastix::SimilarityTransformElastix< TElastix >::CreateDerivedTransformParameterMap ( ) const

overrideprivatevirtual

Creates a map of the parameters specific for this (derived) transform type.

Implements elastix::TransformBase< TElastix >.

elxClassNameMacro()

template<typename TElastix>

elastix::SimilarityTransformElastix< TElastix >::elxClassNameMacro

(

"SimilarityTransform"

)

Name of this class. Use this name in the parameter file to select this specific transform.
example: (Transform "SimilarityTransform")

InitializeTransform()

template<typename TElastix>

void elastix::SimilarityTransformElastix< TElastix >::InitializeTransform ( )

private

Initialize Transform.

• Set all parameters to zero.
• Set center of rotation: automatically initialized to the geometric center of the image, or assigned a user entered voxel index, given by the parameter (CenterOfRotation <index-x> <index-y> ...); If an initial transform is present and HowToCombineTransforms is set to "Compose", the initial transform is taken into account while setting the center of rotation.
• Set initial translation: the initial translation between fixed and moving image is guessed, if the user has set (AutomaticTransformInitialization "true").

It is not yet possible to enter an initial rotation angle.

ITK_DISALLOW_COPY_AND_MOVE()

template<typename TElastix>

elastix::SimilarityTransformElastix< TElastix >::ITK_DISALLOW_COPY_AND_MOVE
