[Gimp-user] Deblurring an out-of-focus image

[Helmut Jarausch <jarausch skynet be>]

Hi,

I have several scripts, plug-ins and more (G'MIC) for deblurring an  
image which is (slightly) out of focus.
But then someone showed me the result of applying Topaz Sharpen AI on  
an image of my own.
It was really impressing.

Unfortunately, I cannot use Topaz Sharpen AI since it doesn't run on  
Windows running in a VM (Virtualbox)
and I don't have a native Windows here.

Does anybody know something which comes close to Topaz Sharpen AI  
(either on Windows running in a VM
or even better running in Gimp or G'MIC)?

Many thanks for a hint,
Helmut
