[Insight-developers] error in itkEigenAnalysis2DImageFilter

[Tomáš Kazmar]

Hi all,

  I think the first line of the following excerpt from ITK3.2.0
itkEigenAnalysis2DImageFilter::GenerateData() is useless and it could
slow down the computation (if it is not thrown away by compiler). If I am
right it should be removed.

    outputIt3.Set( eigenVector );

    const VectorComponentType norm = eigenVector.GetNorm();
    if( norm > 1e-30 ) 
      {
      outputIt3.Set( eigenVector / norm  );
      }
    else
      {
      outputIt3.Set( nullVector );
      }
