Detailed Description

template<typename TCoordRep, unsigned int VSpaceDimension, typename TImage = Image< double, VSpaceDimension >>
class itk::PCAShapeSignedDistanceFunction< TCoordRep, VSpaceDimension, TImage >

Compute the signed distance from a N-dimensional PCA Shape.

This class computes the signed distance from a N-dimensional shape defined by: (1) a mean signed distance image $ M(x) $ , (2) the first $ q $ principal components images $ P_i(x) $ and (3) a transform $ T(x) $ to define the pose (i.e. position or orientation of the shape).

A particular instance of the shape is defined by a set of parameters $ p $ . The first $ q $ parameters defines the weights applied to each principal components and the remaining parameters is used to define the transform. The user should refer to the documentation of the particular Transform class being used. The first set of parameters are called the ShapeParameters and the remaining parameters the PoseParameters.

The method Evaluate( point x ) returns the approximate signed to the shape at point x such that:

$s = M(T(x)) + \sum_i^{q} p[i] * \sigma[i] * P_i(T(x))$

Where $\sigma[i]$ are the square root of the eigenvalues. These are defined using method SetPrincipalComponentStandardDeviations().

This class is templated over the coordinate representation type (e.g. float or double) and the space dimension.
