How to deblur an image?

I am a new to this field. What I know so far is that I should use Wiener Filter to deblur an image. But I don't have a clear picture so it is impossible for me to use PSF(as suggested by others). Is there any way to deblur the image with only raw blurred image?

You can also use deconvlucy(). Basically if you don't know the PSF in advance, then you can just guess until you figure out the output image that looks best.

Hello Analyst, since deconvlucy() has many parameter format such as

if true
J = deconvlucy(I, PSF);
J = deconvlucy(I, PSF, NUMIT);
J = deconvlucy(I, PSF, NUMIT, DAMPAR);
J = deconvlucy(I, PSF, NUMIT, DAMPAR, WEIGHT)
J = deconvlucy(I, PSF, NUMIT, DAMPAR, WEIGHT, READOUT)
J = deconvlucy(I, PSF, NUMIT, DAMPAR, WEIGHT, READOUT, SUBSMPL);

 However, it is still require the PSF, since I only have blurred image, how do you analyze or guess the value?Thank you very much!

Perhaps guess until the standard deviation is maximized - this will be the image with the most details perhaps.
