Determine point spread function from pixel distribution information

I am looking to convert an image to a Gaussian point-spread function. I have both the image and the pixel information but am unfamilar with MathLab. Any tips would be extremely helpful. Thanks!

If you don’t know the original PSF in advance, then you can try random PSF by tweaking various parameters of the fspecial() function until you figure out which PSF is giving the best deblurring. However, for Gaussian filtering of images imgaussfilt() is better recommended. You can go through those links to see if thats what you require!
