I resample the images to twice the pixel resolution, then align these to a specified accuracy using a DFT method (see Manuel Guizar-Sicairos, Samuel T. Thurman, and James R. Fienup, "Efficient subpixel image registration algorithms," Opt. Lett. 33, 156-158 (2008).), I am currently using 1/2 pixel accuracy. I then average the 4 images.

I’ll tell Manuel that his algorithm is used “in the wild”, he works at the same institute as I do: http://www.psi.ch/media/from-inside-an-eggshell


I had a yarn with Manual some time back, regarding the use of his code and some minor changes to allow it work OK in Octave.
