does anyone know of any good software or mathematical algorithms for image deconvolution?

i have a number of photographs of scenery in alaska, which were taken with a cheap cell phone camera, came out rather blurry, and which i wish to place in the public domain for this purpose.

i am wondering if there is a simple image processing algorithm to deconvolve them about a fixed circular aperture kernel. there is a website devoted to such matters

http://www.deconvolve.net/
http://www.bialith.com/


but it is quite outdated, refers to software that only runs on ms windows, and furthermore smacks of medical quackery, which i wish to avoid at all costs....

^EDIT: i am also interested in any discussion or pointers to mathematical algorithms that are used for such deconvolution, as i would be interested in programming and implementing them myself

The GMIC add on to the GIMP has a deconvolution plugin. I don't know how well it works.

Thank you. I may file this away in the back of my mind for future use, but yes I am still interested in code or algorithms or source with comments. I read a paper on it years ago that somehow got "declassified" and picked up by google from some misconfigured military server somewhere.

You might be interested in looking at OpenCV (the computer vision library).

(I only have a fairly old version of the manual, and did not see a reference to deconvolution, but there might be something in the source you could use.)
