How do i estimate the power spectral density of an image masked by white Gaussian noise. i need sample code for the iterative weiner filter

You can use pwelch() or fft() to see the spectrum. With white noise, the spectrum should be pretty flat. I don't have any code handy that uses wiener filter to home in on the noise spectrum alone.
