[Insight-developers] ITK 3.12: FREEZING TODAY ( Hessian 2D Warnings )

[Luis Ibanez]

Bill,

Good point,
This silences the warning.

The modification has been committed:
http://www.itk.org/cgi-bin/viewcvs.cgi/Code/BasicFilters/itkHessianRecursiveGaussianImageFilter.txx?root=Insight&r1=1.8&r2=1.9&sortby=date

It still doesn't really solve the underlying problem,
but it will pacify the dashboard.

After the release we will look back and consider:

    1) A template specialization for 2D
    2) Add concept checking to prevent 1D instantiations.


  Thanks


     Luis
