[Insight-users] itkSymmetricEigenAnalysisImageFilter

[jing xu]

II use ITK to extract the centreline of 3D vessel ,The basic theory is to
calculate the Hessian matrix of  image at scale
Then
lamda1<lamda2<lamda3  and  lamda1<lamda2<0
The scale product of eigenvector1 and gradient of image is equal to zero
The scale product of eigenvector2 and gradient of image is equal to zero
But in ITK software, I only find function
itkSymmetricEigenAnalysisImageFilter to deal with 3D  Hessian matrix and
there is no method to get the eigenvector
I want to know there is any other fuction to get the eigenvector of 3D
Hessian matrix
Thank you
