Methods

virtual
void
compute(
    InputArray image,
    OutputArray result,
    Stream& stream = Stream::Null()
    ) = 0

Computes an FFT of a given image.

Parameters:

image	Source image. Only CV_32FC1 images are supported for now.
result	Result image.
stream	Stream for the asynchronous version.
