That would sure help make the image processing faster, but techniques do
exist for image registration (e.g. http://bishopw.loni.ucla.edu/). This is
often required for MRI or electron microsope images since the movement of
the apparatus affects the image scale, skew and focus. But, if you can skip
this step, you'll get to the final image a lot faster.
