Based on: Fourier Mellin Image Registration by Robinson Laundon which is in turn based on Fourier-Mellin based Image Registration (with GUI) by Adam Wilmer
Improvements:
  • Separated computations from image loading/display
  • Peak interpolation for better accuracy
  • Support for arbitrary image pixel precision format
  • Minor code cleanup
  • Bugfix to make code produce proper translation for non-square images
Note: input images should be grayscale and of the same width/height

Version Published Release Notes
1.0.1

- fix to compute precise small values of scale and rotation
- added parameter to specify which interpolation method to use internally
- phase correlation produced poor results for my data, so added option to use signal cross-correlation
