[Insight-users] itkVectorGradientMagnitudeImageFilter

[Reinhard Hameeteman]

Hi all,

I think the doxygen documentation of
itkVectorGradientMagnitudeImageFilter is not correct. With respect to
the automatically generated third template parameter it is stated that

Given an M-channel input image with dimensionality N, and a numerical
type specified as TRealType, the output image will be of type
itk::Image<itk::Vector<TRealType, M>, N>.

While the source code reads

00132 template < typename TInputImage,
00133            typename TRealType = float,
00134            typename TOutputImage = Image< TRealType,
00135
::itk::GetImageDimension<TInputImage>::ImageDimension >
00136 >
00137 class ITK_EXPORT VectorGradientMagnitudeImageFilter :
00138     public ImageToImageFilter< TInputImage, TOutputImage >

Which means that the output image is a scalar image with
dimensionality equal to the input image and pixeltype equal to the
second template parameter and not an image with vector pixel type.

Greetings,
