At the last meeting we briefly discussed what image types should be wrapped
by Swig when someone builds ITK out of the box. The user always has the
option of adding more image types later and adding more filter
instantiations. But we still need to pick a good set of image types that
are immediately useful.
Here is a set of suggestions:
2D/3D float images - standard datatype used to avoid precision problems, PET
images are floating point
2D/3D short images - CT images (HU) are signed short
2D/3D unsigned short images - MR images are unsigned short (?), PNG images
are unsigned, label maps are unsigned
2D/3D unsigned char images - PNG images are unsigned char
2D/3D unsigned long - label maps are unsigned and can easily overflow an
unsigned short
(Plus some RGB types)
I think these basic image types should be wrapped. Then the question is how
many combinations of instantiations for filters should be do?
