[Insight-developers] GaussianFilter::NormalizeAcrossScale not good for scale space analysis

[Bradley Lowekamp]

Hello all,

I have completed a major revision to itkGaussianDerivativeOperator and submitted a couple of patches to gerrit:

http://review.source.kitware.com/#change,660
http://review.source.kitware.com/#change,661

This patch is a needed algorithmic revision to produce accurate results.

I still need to modify my recursive gaussian scale space test to test the discrete functions. But without that,  I am still extremely confident in the the results form this operator are correct and robust with it's parameters as it's values are extremely close to the values I am getting with the recursive hessian filter for my scale space program.
