RETURN TYPEPoint2d

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Detects translational shifts between two images.

This function extends the standard phaseCorrelate method by improving sub-pixel accuracy through iterative shift refinement in the phase-correlation space, as described in [hrazdira2020iterative].
