ImagePeriodogram

ImagePeriodogram[image] shows the squared magnitude of the discrete Fourier transform (power spectrum) of image.

ImagePeriodogram[image,n] shows the average of power spectra of non-overlapping partitions of size n×n.

ImagePeriodogram[image,n,d] uses partitions with offset d.

ImagePeriodogram[image,n,d,wfun] applies a smoothing window wfun to each partition.

ImagePeriodogram[image,n,d,wfun,m] pads partitions with zeros to length m prior to the computation of the transform.
