WebFeb 16, 2024 · Most FFT tools provide a shift function to circularly shift your result so that the 0Hz component is in the center. In pytorch you need to perform torch.fft.fftshift after the FFT and torch.fft.ifftshift right before taking the inverse FFT to put the 0Hz component back in the upper left corner.
