class foscat.scat_cov2D.funct(*args, **kwargs)[source]#

Bases: foscat.scat_cov.funct

spectrum(image)[source]#

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
