The function assumes that a voxel in one image corresponds exactly
with the same voxel in another. This is not a safe assumption if
the orientation information in the headers or .mat files says that
the images are oriented differently. Please ensure that you process
all data correctly. For example, you may have realigned the images,
but not actually resliced them to be in voxel-wise alignment.
