[Insight-users] Gatens Label Object Representation and Manipulation

[Christian Werner]

Hi!

Yes, USE_REVIEW is on I am sure about that since I already built some 
libraries. I am using Debian Lenny and gcc 4.4.3. But maybe it is only 
because I misunderstand something.

I see that I need label objects anyway, so it does not harm if I include 
them in my own code. But I was really confused about getting errors when 
just including a single header. Shouldn't this header take care of his 
own dependencies?

Anyway, these 3 lines are the very beginning of my labeling try and 
these already produce errors:

typedef itk::Image< unsigned char,  2 >   InputImageType;
...
56  typedef ShapeLabelObject<unsigned char, 2> LabelObjectType;
57  typedef LabelMap< LabelObjectType >        LabelMapType;
58  typedef itk::BinaryImageToLabelMapFilter<InputImageType, 
LabelMapType> ImageToLabelType;
59  //2)
60  ImageToLabelType::Pointer image2LabelMap = ImageToLabelType::New();

Compiler Errors:
/home/christian/programming/itk/labeling/testITK.cxx: In function ‘int 
main(int, char**)’:
/home/christian/programming/itk/labeling/testITK.cxx:56: error: expected 
initializer before ‘<’ token
/home/christian/programming/itk/labeling/testITK.cxx:57: error: expected 
initializer before ‘<’ token
/home/christian/programming/itk/labeling/testITK.cxx:58: error: 
‘LabelMapType’ was not declared in this scope
/home/christian/programming/itk/labeling/testITK.cxx:58: error: template 
argument 2 is invalid
/home/christian/programming/itk/labeling/testITK.cxx:58: error: invalid 
type in declaration before ‘;’ token
/home/christian/programming/itk/labeling/testITK.cxx:60: error: expected 
initializer before ‘image2LabelMap’

Maybe I don't get this labeling right... ?

This is what I include now:

#include "itkImageToImageFilter.h"
#include "itkShapeLabelObject.h"
#include "itkLabelMap.h"
#include "itkBinaryImageToLabelMapFilter.h"
#include "itkLabelMapToRGBImageFilter.h"
