Here is a link to a company which sells maximum entropy
deconvolution software
http://www.cyanogen.on.ca/maximdl.html
I have no connection to this company and have not
used the software. But the demo is free so why not
give it a try.
I have an image at home with some motion blur which I
will try the demo on over the holidays.
