Hello to everyone,
I am trying to read an input image, using a reader object. Then devide the
image, using neighborhood iterator and finally, find the max value of every
neighborhood iterator and get it on my command prompt window. I think that
this can be done wtith the following code, but when I build it, it doesn't
recognise the ' < ' operator.  Can somebody help me? (I use visualstudoi
2010 and Cmake)

thnaks in advance

    if(argc < 2)
    {
    std::cerr << "Required: filename" << std::endl;

    }

  typedef itk::Image<unsigned char, 2>  ImageType;

  typedef itk::ImageFileReader<ImageType> ReaderType;
  ReaderType::Pointer reader = ReaderType::New();

  itk::ConstNeighborhoodIterator<ImageType> inputIterator(radius,
image,region);



  while(!inputIterator.IsAtEnd())

ImageType::IndexType max = inputIterator.GetIndex(0);

    for(unsigned int i = 1; i < 9; i++)
      {
