Are you doing phase correlation, or cross-correlation in the image
domain?  If so, I wonder if you can build on top of the existing
template matching algorithm to use that as an initial value from which
to start the subpixel search?

Anyway, always keen to be able to do better alignment, and would love
to build out the registration capabilities in scikit-image.

Thanks for getting in touch!
