vpi.Image.irfft

Image.irfft(self: vpi.Image, size: Optional[Tuple[int, int]] = None, *, denorm: bool = False, backend: vpi.Backend = vpi.Backend.DEFAULT, stream: vpi.Stream = None) → vpi.Image

Runs the inverse (real) FFT on the image.

It runs the inverse Fast Fourier Transform (FFT) algorithm on the image generating an output image with real numbers.

Parameters

  • size (Tuple[int, int], optional) – The dimensions (width, height) of the output image.

  • denorm (bool, optional) – Output is left denormalized if True.

  • backend (vpi.Backend, optional) – The backend to be used by the algorithm.

  • stream (vpi.Stream, optional) – The stream to be used by the algorithm.

Returns

The output for the algorithm.

Return type
