Dear ITK users,<div><br></div><div>I'm trying to use the version of itkGaussianDerivativeOperator included in ITK3.20. </div><div>Browsing the source and trying to use the class, I noticed that setting the flag SetNormalizeAcrossScale to true doesn't affect the 0 order derivative, i.e. the kernel of 0 zero order is the same with or without SetNormalizeAcrossScalet setted to true. </div>
<div>In my knowledge using scale space normalization means that the Gaussian (0 order derivative), used for the convolution, is not normalized to 1 as usual, but its normalization is equal to sigma^n, where sigma is the std deviation of the gaussian and n is the number of dimensions of the kernel. Is this correct?</div>
<div>I'll be very grateful if someone can explain to me this reason of this implementation.</div><div><br></div><div><br></div><div>Thank you and best regards</div><div><br></div><div>Niccolo' Camarlinghi</div>
