- | After classification step different classes might contain the same view, but rotated in the image plane, so alignment is needed for the same views to look identical. | + | After a classification step different classes might contain the same view, but rotated in the image plane (i.e. different α-angles), so an alignment is needed to optimize the class averages before using them as references for image alignment. |
