Hi Philippe,
to answer your question more elaborately: The return image of FD
Math>Correlate does not contain information about rotation or tilt. You
cannot correct for rotation and tilt with the return image of FD
Math>Correlate. Do you mean shear when you say tilt?.
If you like to stick with FD, there is a not so robust possibility to
identify rotation. Polar-transform the FTs of both images and then do
FD Math>Correlate to identify their translation. This translation
corresponds to the angle of rotation, not the translation.
For efficient information about writing the lines in your own code study
the code and references of the mentioned plugins that all implement
efficient solutions to this problem.
Cheers,
Stephan
