Hi Olfa,
I’m not sure what you refer to when writing about segmentation models. In case
of segmentation images you wouldn’t lose any information, as for example the
nrrd image format preserves the origin in its header. In case of surface models
most file formats do not support this extra information and as such the
absolute coordinates are saved instead. When loading both into MITK, the
original image and the surface model they are aligned again, even though the
coordinates of the surface model are relative to the absolute origin now.
Best,
Stefan

Subject: [mitk-users] MITK segmentation
hello everybody,
I am actually using the MITK software to get a segmented model (of a specific
organ). The problem is that when we segment an object in MITK we loose
information about the original position of the object. I tried to get the
original position and orientation by applying the 'translate' vector and the
'Direction Matrix' to the model. But unfortunately it doesn't work.
Please can anyone help me to understand how MITK do to initialize the position
and orientation of a segmented model.
Any answer will be welcome do not hesitate if you have any idea. Thank you.
Have a nice day.
