   .. py:method:: spectrum(image)

      Compute the 1D power spectrum of a 2D image by averaging the 2D power spectrum
      over concentric frequency rings (radial averaging), using np.bincount for efficiency.

      Parameters:
      - image : ndarray (2D), input image

      Returns:
      - freq : radial frequencies
      - spectrum_1d : corresponding 1D power spectrum



   .. py:method:: plot_results(in_image, out_image, vmin=None, vmax=None, cmap='coolwarm', spec_range=None)
