This method is equally robust to noise as the standard FFT upsampling, but much faster. It computes the same upsampled cross correlation but only in a small neighborhood around the peak.

23 May 2013 Efficient subpixel image registration by cross-correlation Registers two images (2-D rigid translation) within a fraction of a pixel specified by the user. Author: Manuel Guizar Tom Wright

This is great. I made a few minor modifications to limit translation to only the x or y axis. Do you have this under version control anywhere?
