Hi Luis,
I am getting this very strange error message while compiling. Can you
explain what this could be?

/home/rsivaram/Insight/Code/Common/itkInPlaceImageFilter.txx: In member
   function `void itk::InPlaceImageFilter<TInputImage,
   TOutputImage>::AllocateOutputs() [with TInputImage = main(int,
   char**)::IntImageType, TOutputImage = main(int, char**)::ImageType]':
/home/rsivaram/Insight/Code/Common/itkImageRegion.h:173:   instantiated from
here
/home/rsivaram/Insight/Code/Common/itkInPlaceImageFilter.txx:76: no matching
   function for call to `itk::InPlaceImageFilter<main(int,
   char**)::IntImageType, main(int,
char**)::ImageType>::GraftOutput(main(int,
   char**)::IntImageType*)'
/home/rsivaram/Insight/Code/Common/itkImageSource.txx:95: candidates are:
void
   itk::ImageSource<TOutputImage>::GraftOutput(TOutputImage*) [with
   TOutputImage = main(int, char**)::ImageType]

Thanks
Radhika

Hi Radhika,

Resistance if futile...

The solution in this case is not to remove
the existing 'const' but to  add new ones.

The real issue here is that the method Quantile()
should be 'const', since it simply computes a
double using existing information from the Histogram.
This methods doesn't change the content nor the state
of the Histogram.

The 'const' declaration has been added to the
itkHistogram.h and .txx files in the CVS
repository. You may want to update your checkout
in order to get these modifications.

Please let us know if you find any further
problems.

   Thanks

     Luis

&gt; Hi Luis,
 &gt; 
 &gt; I adapted the example ImageHistogram2.cxx which uses 
 &gt; ScalarImagetoHistogramGenerator to generate a histogram from a 3D image. 
 &gt; I wanted to next threshold the image
 &gt; 
 &gt; using a threshold which I hoped to derive by using the Quantile 
 &gt; function. But I am getting a compile error:
 &gt; 
 &gt;&nbsp; 
 &gt; 
 &gt; HistogramThreshold.cxx:125: passing
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; `const main(int, char**)::HistogramType' as `this' argument of `double
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; itk::Statistics::Histogram&lt;TMeasurement, VMeasurementVectorSize,
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; TFrequencyContainer&gt;::Quantile(unsigned int, const double&amp;) [with
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; TMeasurement = double, unsigned int VMeasurementVectorSize = 1,
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; TFrequencyContainer = itk::Statistics::DenseFrequencyContainer&lt;float&gt;]'
 &gt; 
 &gt;&nbsp;&nbsp;&nbsp; discards qualifiers
 &gt; 
 &gt;&nbsp; 
 &gt; 
 &gt; I thought it might be a &quot;const&quot; problem so I removed all the const 
 &gt; declarations but I still got a similar error.
 &gt; 
 &gt; Can you help me figure out what the problem is?
 &gt; 
 &gt;&nbsp; 
 &gt; 
 &gt; Thanks
 &gt; 
 &gt; Radhika
