Detailed Description

template<typename TInputImage, typename TOutputImage = Image< double, TInputImage::ImageDimension >>
class itk::ImagePCAShapeModelEstimator< TInputImage, TOutputImage >

Base class for ImagePCAShapeModelEstimator object.

itkImagePCAShapeModelEstimator performs a principal component analysis (PCA) on a set of images. The user specifies the number of training images and also the number of desired largest principal components needed. The ITK pipeline mechanism sets up the storage for both input and output images. The number of output images are the user specified number of desired largest principal components plus 1 (for the mean image).

The algorithm uses the VNL library to perform the eigen analysis. To speed the computation of the instead of performing the eigen analysis of the covariance vector A*A' where A is a matrix with p x t, p = number of pixels or voxels in each images and t = number of training images, we calculate the eigen vectors of the inner product matrix A'*A. The resulting eigen vectors (E) are then multiplied with the the matrix A to get the principal compoenets. The covariance matrix has a dimension of p x p. Since number of pixels in any image being typically very high the eigen decomposition becomes computationally expensive. The inner product on the other hand has the dimension of t x t, where t is typically much smaller that p. Hence the eigen decomposition (most compute intensive part) is an orders of magnitude faster.

The Update() function enables the calculation of the various models, creates the membership function objects and populates them.

Local functions A function that generates the cluster centers (model) corresponding to the estimates of the cluster centers (in the initial codebook). If no codebook is provided, then use the number of classes to determine the cluster centers or the Shape model. This is the the base function to call the K-means classifier.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage, typename TOutputImage = Image< double, TInputImage::ImageDimension >>
virtual void itk::ImagePCAShapeModelEstimator< TInputImage, TOutputImage >::SetNumberOfPrincipalComponentsRequired ( unsigned int  n)
virtual

Set/Get the number of required largest principal components. The filter produces the required number of principal components plus one outputs. Output index 0 represents the mean image and the remaining outputs the requested principal components.

template<typename TInputImage, typename TOutputImage = Image< double, TInputImage::ImageDimension >>
virtual void itk::ImagePCAShapeModelEstimator< TInputImage, TOutputImage >::SetNumberOfTrainingImages ( unsigned int  n)
virtual

Set/Get the number of training images in the input.
