Hello again!
Because my program complained of not having enough grey values for the amount
of lables when I tested it on a 3D image I changed the output pixel type to
unsigned short.
The itk::MaskImageFilter was not happy with different input and ouput types
(is this a bug?) so I changed the input type to unsigned as well. Now no
complains during compile time any more but the output of
LabelOverlayImageFilter of the scaled (ouput unsigned short) distance map
looks wrong. Is this a bug as well? I attached the two ouputs.
It works fine even with unsigned short if I let the scaler only scale up to
255L and not up to 65535L.
Another question: Is the amount of labels from
MorphologicalWatershedFromMarkersImageFilter only limited by what the ouput
pixel type can store?
Regards,
Lynx
