vpi.Image.fft

Image.fft(self: vpi.Image, *, backend: vpi.Backend = vpi.Backend.DEFAULT, out: vpi.Image = None, stream: vpi.Stream = None) → vpi.Image

Runs the direct FFT on the image.

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