Please, not just for my headache's sake, but for Abdulcadir to get the help he kindly requests without people having to read this tripe, please, no more MP discussion. And fornzix, along with being a published photographer, I am an expert in digital photography (in fact, if you spend real money on your forensics software, you're using software I wrote to cull your EXIF data).

So please, no more megapixel discussion. The horse is quite dead.

Heard of a product called Ikena, that looked pretty good at unblurring and sharpening up images using frame analysis etc.

A tangent topic, it may be, but to give advice that the math underlying this topic is in any form easily understandable is quite negligent and misleading. Hence, I gave a scientific paper as a point of reference. Ad hominem arguments are to skirt the subject and attack the person; if this is how you took it, I do hope you understand it was not meant as such.

As far as I know, GIMP's basic unsharp mask does not use fourier transform, but a single gaussian function blurred mask.

Even if it used navier-stokes, I do not need to find a jury or group of peers who will grasp the the complete details. I only need to find one that accept the tool or function to be functional, consistent and produces factual results.

It would be detrimental to most cases to start blabbering about gaussian blur, curves, how particles on platters are line up to form data, pits on CDs generate spiral grove, NAND gates in flash drives, etc. I can just see & hear glazed over eyes and snoring.

Most jury is quite content with accepting that a "black box or function" works, and works consistently.

fornzix, you are right. No corruption of the evidence worth "trying".

Here's an interesting link to an article that just came out in Forensic Magazine on "Video Enhancement of Facial Images".

http//www.forensicmag.com/articles.asp?pid=199

The approach here was to get a forensic artist to watch the video and do a pencil & paper sketch. Interesting results…

There's an email link to the IAI Forensic Artist who wrote the article and did the work. (Forensic Science Laboratory, Oakland County Sheriff’s Office)

You might want to send her an email if you think that this approach would work for you.
