[ITK] [ITK-users] max min image matrix

[Mike Chinander]

Since the image type is unsigned char, cout is interpreting the values of
GetMaximum() and GetMinimum as chars. Cast the result to int before sending
to cout:

  std::cout << "Min: " <<
static_cast<int>(statisticsImageFilter->GetMinimum()) << std::endl;
  std::cout << "Max: " <<
static_cast<int>(statisticsImageFilter->GetMaximum()) << std::endl;
