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