Detailed Description

template<class TDataset, class TScalarType, unsigned int TInputDimension, unsigned int TOutputDimension = TInputDimension>
class itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >

Base class that implements an itk transform interface for statistical models.

Statistical models (shape or deformation models) are often used to model the typical variations within an object class. The StatisticalModelTransformBase implements the standard Transform interface, and thus allows for the use of statistical models within the ITK registration framework. Subclasses will need to implement the TransformPoint method, as its semantics depends on the type of statistical model.

virtual void itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::CopyBaseMembers ( StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension > *  another ) const

inlinevirtual

Copy the members of the current transform. To be used by subclasses in the CreateAnother method.

virtual VectorType itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::GetCoefficients ( ) const

inlinevirtual

Convenience method to obtain the current coefficients of the StatisticalModel as a statismo::VectorType. The resulting vector is the same as it would be obtained from GetParameters.

template<class TDataset, class TScalarType, unsigned int TInputDimension, unsigned int TOutputDimension = TInputDimension>

virtual const ParametersType& itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::GetFixedParameters ( void  ) const

inlinevirtual

returns an empty Parameter vector, as the tranform does not have any fixed parameters

virtual void itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::SetCoefficients ( VectorType &  coefficients )

inlinevirtual

Convenicne method to set the coefficients of the underlying StatisticalModel from a statismo::VectorType. This has the same effect as calling SetParameters.

template<class TDataset, class TScalarType, unsigned int TInputDimension, unsigned int TOutputDimension = TInputDimension>

virtual void itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::SetFixedParameters ( const ParametersType &  p )

inlinevirtual

Does nothing - as the transform does not have any fixed parameters

void itk::StatisticalModelTransformBase< TRepresenter, TScalarType, TInputDimension, TOutputDimension >::SetIdentity ( void  )

virtual

Set the parameters to the IdentityTransform

Set the parameters to the IdentityTransform.

void itk::StatisticalModelTransformBase< TRepresenter, TScalarType, TInputDimension, TOutputDimension >::SetParameters ( const ParametersType &  parameters )

virtual

Set the parameters of the transform

void itk::StatisticalModelTransformBase< TRepresenter, TScalarType, TInputDimension, TOutputDimension >::SetStatisticalModel

(

const StatisticalModelType *

model

)

Set the statistical model that defines the valid transformations.

Set the morphable model and ajust the parameters dimension.

void itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::SetUsedNumberOfCoefficients ( unsigned  n )

inline

Set the number of PCA Coefficients used by the model. This parameters has a regularization effect. Setting it to a small value will restrict the possible tranformations to the main modes of variations.

template<class TDataset, class TScalarType, unsigned int TInputDimension, unsigned int TOutputDimension = TInputDimension>

virtual OutputPointType itk::StatisticalModelTransformBase< TDataset, TScalarType, TInputDimension, TOutputDimension >::TransformPoint ( const InputPointType &  pt ) const

pure virtual

Transform a given point according to the deformation induced by the StatisticalModel, given the current parameters.

Parameters

pt	The point to tranform

Returns

The transformed point

Implemented in itk::InterpolatingStatisticalDeformationModelTransform< TDataset, TScalarType, TDimension >, itk::StatisticalShapeModelTransform< TRepresenter, TScalarType, TDimension >, and itk::StatisticalDeformationModelTransform< TDataSet, TScalarType, TDimension >.
