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.
