#include <itkImagePCADecompositionCalculator.h>
Decomposes an image into directions along basis components.
This calculator computes the projection of an image into a subspace specified by some basis set of images, and, optionally, a mean image (e.g a translation to a new origin). Typically, this basis/mean image will be the mean and principal components of an image data set, as calculated by an ImagePCAShapeModelEstimator. The output of the calculator is a vnl_vector containing the coefficients along each dimension of the provided basis set. To use this calculator, set the basis images with the SetBasisImage method, and optionally set the mean image with the SetMeanImage method. In the PCA case, the zeroth output of the ImagePCAShapeModelEstimator is the mean image and subsequent outputs are the basis images. SetBasisFromModel is a convenience method to set all of this information from a given ImagePCAShapeModelEstimator instance.
This class is templated over the input image type and the type of images used to describe the basis.
