Detailed Description

aligns a set of pointsets together

vtkProcrustesAlignmentFilter is a filter that takes a set of pointsets (any object derived from vtkPointSet) and aligns them in a least-squares sense to their mutual mean. The algorithm is iterated until convergence, as the mean must be recomputed after each alignment.

vtkProcrustesAlignmentFilter requires a vtkMultiBlock input consisting of vtkPointSets as first level children.

The default (in vtkLandmarkTransform) is for a similarity alignment. For a rigid-body alignment (to build a 'size-and-shape' model) use:

GetLandmarkTransform()->SetModeToRigidBody().

Affine alignments are not normally used but are left in for completeness:

GetLandmarkTransform()->SetModeToAffine().

vtkProcrustesAlignmentFilter is an implementation of:

J.C. Gower (1975) Generalized Procrustes Analysis. Psychometrika, 40:33-51.

Warning: All of the input pointsets must have the same number of points.

static

Creates with similarity transform.

virtual vtkLandmarkTransform* vtkProcrustesAlignmentFilter::GetLandmarkTransform ( )

virtual

Get the internal landmark transform. Use it to constrain the number of degrees of freedom of the alignment (i.e. rigid body, similarity, etc.). The default is a similarity alignment.

virtual vtkPoints* vtkProcrustesAlignmentFilter::GetMeanPoints ( )

virtual

Get the estimated mean point cloud

virtual void vtkProcrustesAlignmentFilter::SetStartFromCentroid ( bool )

virtual

When on, the initial alignment is to the centroid of the cohort curves. When off, the alignment is to the centroid of the first input. Default is off for backward compatibility.

virtual bool vtkProcrustesAlignmentFilter::GetStartFromCentroid ( )

virtual

When on, the initial alignment is to the centroid of the cohort curves. When off, the alignment is to the centroid of the first input. Default is off for backward compatibility.

virtual void vtkProcrustesAlignmentFilter::StartFromCentroidOn ( )

virtual

When on, the initial alignment is to the centroid of the cohort curves. When off, the alignment is to the centroid of the first input. Default is off for backward compatibility.

virtual void vtkProcrustesAlignmentFilter::StartFromCentroidOff ( )

virtual

When on, the initial alignment is to the centroid of the cohort curves. When off, the alignment is to the centroid of the first input. Default is off for backward compatibility.

virtual void vtkProcrustesAlignmentFilter::SetOutputPointsPrecision ( int )

virtual

Set/get the desired precision for the output types. See the documentation for the vtkAlgorithm::DesiredOutputPrecision enum for an explanation of the available precision settings. If the desired precision is DEFAULT_PRECISION and any of the inputs are double precision, then the mean points will be double precision. Otherwise, if the desired precision is DEFAULT_PRECISION and all the inputs are single precision, then the mean points will be single precision.

virtual int vtkProcrustesAlignmentFilter::GetOutputPointsPrecision ( )

virtual

Set/get the desired precision for the output types. See the documentation for the vtkAlgorithm::DesiredOutputPrecision enum for an explanation of the available precision settings. If the desired precision is DEFAULT_PRECISION and any of the inputs are double precision, then the mean points will be double precision. Otherwise, if the desired precision is DEFAULT_PRECISION and all the inputs are single precision, then the mean points will be single precision.
