Dear users, After I built the individual Hessian components, in what order should I fill them up to further feed into the SymmetricEigenAnalysisImageFilter? At the moment I am using the order below. H[0] = Dxx H[1] = Dxy H[2] = Dxz H[3] = Dyy H[4] = Dyz H[5] = Dzz Is this correct order? Thanks, Alex
