Detailed Description

Decorator for SV MFFD transformation.

This decorator wraps a SV MFFD transformation but defines its own attributes regarding integration and whether or not to invert the transformation by default. As the SV MFFD is parameterized by a sum of stationary velocities, inverting the transformation is simply achieved by a negative upper integration limit.

CopyFrom()

virtual bool mirtk::PartialMultiLevelStationaryVelocityTransformation::CopyFrom ( const class Transformation *  )

virtual

Copy active transformation parameters (DoFs) from given transformation if possible and return false, otherwise

Displacement() [1/2]

virtual void mirtk::PartialMultiLevelStationaryVelocityTransformation::Displacement ( int  , int  , GenericImage< double > &  , double  , double  = 1, const WorldCoordsImage *  = NULL  ) const

virtual

Calculates the displacement vectors for a whole image domain

Attention

The displacements are computed at the positions after applying the current displacements at each voxel. These displacements are then added to the current displacements. Therefore, set the input displacements to zero if only interested in the displacements of this transformation at the voxel positions.

Reimplemented from mirtk::MultiLevelTransformation.

Displacement() [2/2]

virtual void mirtk::PartialMultiLevelStationaryVelocityTransformation::Displacement ( int  , int  , GenericImage< float > &  , double  , double  = 1, const WorldCoordsImage *  = NULL  ) const

virtual

Calculates the displacement vectors for a whole image domain

Attention

The displacements are computed at the positions after applying the current displacements at each voxel. These displacements are then added to the current displacements. Therefore, set the input displacements to zero if only interested in the displacements of this transformation at the voxel positions.

Reimplemented from mirtk::MultiLevelTransformation.

InverseDisplacement() [1/2]

virtual int mirtk::PartialMultiLevelStationaryVelocityTransformation::InverseDisplacement ( int  , int  , GenericImage< double > &  , double  , double  = 1, const WorldCoordsImage *  = NULL  ) const

virtual

Calculates the inverse displacement vectors for a whole image domain

Attention

The displacements are computed at the positions after applying the current displacements at each voxel. These displacements are then added to the current displacements. Therefore, set the input displacements to zero if only interested in the displacements of this transformation at the voxel positions.

Returns

Always zero.

Reimplemented from mirtk::MultiLevelTransformation.

InverseDisplacement() [2/2]

virtual int mirtk::PartialMultiLevelStationaryVelocityTransformation::InverseDisplacement ( int  , int  , GenericImage< float > &  , double  , double  = 1, const WorldCoordsImage *  = NULL  ) const

virtual

Calculates the inverse displacement vectors for a whole image domain

Attention

The displacements are computed at the positions after applying the current displacements at each voxel. These displacements are then added to the current displacements. Therefore, set the input displacements to zero if only interested in the displacements of this transformation at the voxel positions.

virtual void mirtk::PartialMultiLevelStationaryVelocityTransformation::ParametricGradient ( const GenericImage< double > *  , double *  , const WorldCoordsImage *  , const WorldCoordsImage *  , double  = NaN, double  = 1  ) const

virtual

Applies the chain rule to convert spatial non-parametric gradient to a gradient w.r.t the parameters of this transformation.

Reimplemented from mirtk::Transformation.

ParametricGradient() [2/2]

virtual

Applies the chain rule to convert spatial non-parametric gradient to a gradient w.r.t the parameters of this transformation.

Reimplemented from mirtk::Transformation.

RequiresCachingOfDisplacements()

virtual bool mirtk::PartialMultiLevelStationaryVelocityTransformation::RequiresCachingOfDisplacements ( ) const

virtual

Whether the caching of the transformation displacements is required (or preferred) by this transformation. For some transformations such as those parameterized by velocities, caching of the displacements for each target voxel results in better performance or is needed for example for the scaling and squaring method.

Reimplemented from mirtk::MultiLevelTransformation.
