<BR>
Have a look in the last itk code ( cvs or release ) for the filter "itk::Hessian3DToVesselnessMeasureImageFilter" in files<BR>
itkHessian3DToVesselnessMeasureImageFilter.h and itkHessian3DToVesselnessMeasureImageFilter.txx. It shows you how to perform most of the job: compute hessian then eigenvalues and finally compute some vesselness measure based on eigenvalues.<BR>
<BR>
Best Regards,<BR>

Hi, everyone<BR>
<BR>
I've pasted a message on this class. Just now, I checked that the number of output is 6 values. They should be the component of the hessian matrix. Can someone tell me the order of these values.<BR>
Ixx Ixy Ixz<BR>
Iyy Iyz<BR>
Izz<BR>
Is the order of these value Ixx Ixy Ixz Iyy Iyz Izz? Thanks<BR>
<BR>
<BR>
Have a nice day!<BR>

Sincerly<BR>
