Hello,
I have an image that I would like to downsample, and pad with zeros to
a certain dimension such that the resampled image is centered in the
new image.
I have managed to perform this task, but wonder if my method is
unconventional. My code isn't bloated, but doesn't seem very
intuitive.
I am using itkResampleImageFilter.h and itkIdentityTransform.h.
The filter's OutputSpacing is set as needed. The filter's size is set
to that of the image + the padding. Finally, I set the filter's
origin to a negative value such that the original and resized image is
centred within the larger padded image.
Is there a better way to do this?
Thanks,
Julian
