You might try an interesting new technique based on "pixons".
Dr. R. Puetter developed this technique primarily for deconvolution of
astronomical images, but you should be able to apply it to most
problems. His webpage:

http://cassfos01.ucsd.edu:8080/puetter.html

has references to the IDL source code as well as published articles
which you can download and read. The technique is iterative, a
portion of which is the standard maximum likelihood deconvolution.
You could probably strip this part out if you wanted to.

There are some restrictions for non-scientific use.

Best luck,
Craig
