## Member Function Documentation

## § compute()

virtual void cv::cuda::DFT::compute | ( | InputArray | image,
|  | OutputArray | result,
|  | Stream & | stream = `Stream::Null()`

| pure virtual

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.
