I try to compute eigen vectors of the symmetric matrix corresponding to every input pixel. So, I try to add m_Calculator.ComputeEigenValuesAndVectors(x, eigenValues,eigenvectors) in itkSymmetricEigenAnalysisImageFilter.h. However, it does not work. The data type of eigenvectors is difficult to define for me due to the processing involved in multi-thread.
Hi @TaoH, if you can create a minimal example (sharing the code) of what you are trying to do, there would be more chances of someone giving a hand.
Looking at the unit test should help you.
