GetCovarianceAtPoint(model, pt1, pt2)

GetCovarianceMatrix(model)

GetJacobian(model, pt)

GetProjectionMatrix(model)

## S4 method for signature 'pPCA'
GetPCABasisMatrix(model)

## S4 method for signature 'pPCA'
GetOrthonormalPCABasisMatrix(model)

## S4 method for signature 'pPCA,numeric,numeric'
GetCovarianceAtPoint(model, pt1, pt2)

## S4 method for signature 'pPCA'
GetCovarianceMatrix(model)

## S4 method for signature 'pPCA,numeric'

## S4 method for signature 'pPCA'
GetProjectionMatrix(model)

Arguments

model	model of class "pPCA"
pt1	either an integer pointing to the index of the domain or a numeric vector of length 3 specifying a point on the domain of the model
pt2	either an integer pointing to the index of the domain or a numeric vector of length 3 specifying a point on the domain of the model
pt	either an integer pointing to the index of the domain or a numeric vector of length 3 specifying a point on the domain of the model

Details

see http://statismo.github.io/docs/api/v0.10/html/classstatismo_1_1StatisticalModel.html for details.

Value

GetPCABasisMatrix	returns the (scaled) Basis of the latent space
GetOrthonormalPCABasisMatrix	returns the orthonormal Basis of the latent space
GetCovarianceMatrix	returns the covariance matrix - can be huge!!!
GetCovarianceAtPoint	returns the 3 x 3 covariance matrix for pt1 and pt2
GetJacobian	returns the 3 x 3 Jacobian matrix at pt
GetProjectionMatrix	returns matrix to project a sample vector into the latent space (this is not a member function but might prove useful anyway)
