ximgproc_qdft(img: Mat, qimg: Mat, flags: number, sideLeft: boolean): void;
img

quaternion image.

qimg

Output destination, filled by the native operation. quaternion image in dual space.

flags

quaternion image in dual space. only DFT_INVERSE flags is supported

sideLeft

true the hypercomplex exponential is to be multiplied on the left (false on the right ).
