[Insight-users] How to compute the Hessian?

[Dan Mueller]

Hi Rashed,

Have a look at itkHessianRecursiveGaussianImageFilter: it "computes
the Hessian matrix of an image by convolution with the Second and
Cross derivatives of a Gaussian."

You may also be interested in a paper on the Insight Journal by Luca
Antiga which provides easy to use implementations of both Frangi's and
Sato's "vesselness" filters, which utilise the Hessian matrix across
varying scales:

Cheers, Dan
