Zero-padding the spatial volume to remove the overlapping between the central image and the replicas. In (a), the central part of the visible male dataset is packed in a volume array of the same size. Rotating the volume in (b) results in overlapping. Zero-padding the subvolume removes all the overlapping after rotating the whole volume as shown in (c).
