Part of the research on post anti-blur/shake algorithm, unsharp mask is something I found interesting apart of the sharpening algorithm. here is the thread from Photo.net.

Here is the comparison of the picture. Taken on 18th June 2006 (technical info: Shutter = 1/500s, F-number = 4.5, iso = 200, Focal Length = 45mm, Lens = 28-200mm Tamron LD, Camera=Nikon D50).

Shake? Fuzzy shots? Bad vibrations? Who you gonna call?

A fundamental truism of photography is that the single most effective accessory for sharper shots is the one most universally despised.

The tripod. Your lip curls just reading the word, doesn’t it? Clumsy, unpackable, finger-pinching pests that are heavy if steady, flimsy if light. Damn!

While there’s no substitute for a rock-steady camera support, a magic bullet called image stabilization (or vibration reduction, or optical stabilization, or anti-shake) can help you get sharper handheld shots at shutter speeds that would have once mandated a tripod. Since these systems were first introduced in 1994 (on a Nikon point-and-shoot) and 1995 (in Canon lenses for EOS SLRs), image stabilization has become mainstream technology. So we thought it was worth a thorough look at the current state of the art in anti-shake.

Right, been researching for antishake/blur algorithm for digital camera. Here are some libraries found.
