[Insight-users] Eigenvector computation of Image Hessian

[Karthik Krishnan]

Take a look at the class itk::SymmetricEigenAnalysis. The method
"ComputeEigenValuesAndVectors" computes the eigen vectors as well as the
eigen values for your ND matrix  pixels (the hessians)

You could write a functor just like itk::SymmetricEigenAnalysisImageFilter
does to run this over all the pixels and generate the eigen vector images.
