Implementation
(Point2f rval, double response) phaseCorrelate(InputArray src1, InputArray src2, {InputArray? window}) {
window ??= Mat.empty();
final p = calloc<ffi.Double>();
final pp = calloc<cvg.CvPoint2f>();
cvRun(() => cimgproc.cv_phaseCorrelate(src1.ref, src2.ref, window!.ref, p, pp, ffi.nullptr));
final rval = (Point2f.fromPointer(pp), p.value);
calloc.free(p);
return rval;
