[ITK-users] (newbie) filter SetRadius() compilation issue

[Barbara Post]

Thanks Jon and Luis, you helped me, the following code compiles now.

  typedef  itk::AdaptiveHistogramEqualizationImageFilter<XITKTools::ItkImage3DFloatType> AdaptiveHistogramEqualizationImageFilterType;
          AdaptiveHistogramEqualizationImageFilterType::Pointer adaptiveHistogramEqualizationImageFilter
                  = AdaptiveHistogramEqualizationImageFilterType::New();
          adaptiveHistogramEqualizationImageFilter->SetInput(itkImage);

          XITKTools::ItkImage3DFloatType::SizeType radius;
          radius.Fill(1);

          adaptiveHistogramEqualizationImageFilter->SetRadius(radius);

Dear Barbara,
welcome to the list.
As for the example, it looks like the radius dimensions do not match the image dimensions.

I'd dare to say that your are using a 3D image (ItkImage3DFloatType in your template argument for the histogram equalization filter). Thus, the radius for your filter also requires 3 components.

HTH,
JON HAITZ

Sorry if I'm a newbie, but I have compilation trouble with following wiki example :

http://www.itk.org/Wiki/ITK/Examples/NeedDemo/ImageProcessing/AdaptiveHistogramEqualizationImageFilter

Code from wiki :

typedef  itk::AdaptiveHistogramEqualizationImageFilter<XITKTools::ItkImage3DFloatType> AdaptiveHistogramEqualizationImageFilterType;
          AdaptiveHistogramEqualizationImageFilterType::Pointer adaptiveHistogramEqualizationImageFilter
                  = AdaptiveHistogramEqualizationImageFilterType::New();
          adaptiveHistogramEqualizationImageFilter->SetInput(itkImage);

          adaptiveHistogramEqualizationImageFilter->SetRadius(1);

Compilation error :

error: C2664: 'itk::AdaptiveHistogramEqualizationImageFilter<TImageType>::SetRadius' : cannot convert parameter 1 from 'int' to 'const itk::Size<VDimension>'
with
[
    TImageType=imagx::itktools::XITKTools::ItkImage3DFloatType
]
and
[
    VDimension=3
]
No constructor could take the source type, or constructor overload resolution was ambiguous


Another try :
Change last line in code above to :

      typedef itk::Image<unsigned char, 2> ImageType;
          ImageType::SizeType size;
          size[0] = 1;

          adaptiveHistogramEqualizationImageFilter->SetRadius(size);

Compilation error :

error: C2664: 'itk::AdaptiveHistogramEqualizationImageFilter<TImageType>::SetRadius' : cannot convert parameter 1 from 'itk::Size<VDimension>' to 'const itk::Size<VDimension>'
with
[
    TImageType=imagx::itktools::XITKTools::ItkImage3DFloatType
]
and
[
    VDimension=2
]
and
[
    VDimension=3
]
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Thanks for helping me understanding,

Barbara
