Hi Miri,
I am not quite sure I understand your complaint. I just tried to use the image
cropper on a recent commit and it worked fine for me.
Are you talking about the MITK plugin 'Image Cropper', which is the one I tried?
If you use it to crop a 256x256x256 image by creating a bounding box which just
encompasses the center 64 voxels in each direction you will afterwards have a
64x64x64 image. I am not sure what you mean, when you talk about 'ignoring'
voxels? The image is cropped to the corresponding size, thus the pixels are no
more.
If you want to set the value to zero instead (though cropping should in most
cases speed up the performance/reduce the memory footprint just as much or
more) I would recommend something like thresholding/creating a binary mask and
multiplying the image with it instead.
Regards,
Caspar

Hi all,
So I guess that nobody have ever tried it ?
How it comes? I assume that cropping is an essential tool.
Does MITK's existing module satisfy your needs, although that it just "ignore"
cropped voxels (so the complexity of calculations stays, am I wrong?)?

Hi all,
I'd like to crop my 3d MRI image in order to reduce the complexity of
calculation and save filter's running time.
The mitk's image cropper module sounds like a solution, but the cropped voxels
are only ignored, rather then be set to zero- like I want.
Have anybody already tried to change this module by setting the cropped voxels
to zero ?
Regards,
Miri
