I have a image and I calculated the 2D power spectrum in a ROI of this image. Now I want to get the 1D power spectrum, and it will be show in the spatial frequency.
What I want to do similar with this one:

But I want to show 1D power spectrum like this
I hope you can help me, I really need help.

Can you provide the matrix which has your 2D power spectral density??
If you can explain what you tried and what problem you faced with that method, it will be easier to get answers here
