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.
