Dear Gaëtan,

The exact code is :

typedef itk::RGBPixel<unsigned char>  InputPixelType;
typedef unsigned short LabelPixelType;
typedef itk::Image<InputPixelType,2> InputImageType;
typedef itk::Image<LabelPixelType,2> LabelImageType;
  typedef 
itk::ConnectedComponentImageFilter<InputImageType,LabelImageType> 
ConnectedComponentFilterType;
   ConnectedComponentFilterType::Pointer  connectedComponentFilter = 
ConnectedComponentFilterType::New();

And the exact compilation error is:

/ORFEO/julien/ORFEO-TOOLBOX/otb-hg/OTB/Utilities/ITK/Code/BasicFilters/itkConnectedComponentImageFilter.txx: 
In member function void itk::ConnectedComponentImageFilter<TInputImage, 
TOutputImage, TMaskImage>::ThreadedGenerateData(const typename 
TOutputImage::RegionType&, int) [with TInputImage = 
itk::Image<itk::RGBPixel<unsigned char>, 2u>, TOutputImage = 
itk::Image<short unsigned int, 2u>, TMaskImage = 
itk::Image<itk::RGBPixel<unsigned char>, 2u>]:

VLength>::FixedArray(const TValueType*) [with TValueType = unsigned 
char, unsigned int VLength = 3u]

This was compiling with previous ITK versions (3.8.XX), since the 
compilation error first occured when we upgraded to ITK 3.10.1.

Best regards,
