Point Spread Function of Image

I have an image and I want to get the Point Spread Function for it and then plot it using surface plot. Does anyone know how I can do this?

Take an image of a point source. Or if you know the "true" source and your "noisy, blurry" image, then you can try and inverse filter or a wiener filter. But for just some general image, well, there are probably lots of combinations of images and PSF's that could produce the same image. You could make some assumptions on the PSF and see what you get. Like try deconvlucy().
