* After stacking is completed, the stacked image can be postprocessed
(sharpened) either in a final step of the stacking workflow, or in a

Note that this list can be different for different points.
* For all frames, local shifts are computed at all alignment points.
* Using those shifts, the alignment point patches of all contributing
frames are stacked into a single average image patch.
* Finally, all stacked patches are

by hand as well.
* For each alignment point, all frames are ranked by their local contrast
in a surrounding image patch.
* The best frames up to a given number are selected for stacking.

The following algorithmic steps are performed:

* First, all frames are ranked by their overall image quality.
* On the best frame, a rectangular patch with the most pronounced structure
in x and y is identified automatically. (Alternatively, the user can
select the patch manually as well.)
