Applies inverse affine transformation to an image.


CuviStatus warpAffineBack(const CuviImage& src,
                          CuviImage& dst,
                          Cuvi64f coeffs[2][3],
                          const CuviStream& stream = CuviStream());


Name Type Description
src const CuviImage& Input Image
dst CuviImage& Output Image
coeffs Cuvi64f [2][3] 2 x 3 affine transformation matrix
stream const CuviStream& GPU stream ID for execution
