I haven't been able to find the article to respond. The caller had used digital techniques to reproduce the writing in an old book (I believe) and was searching for a public domain package for enhancing that image. I passed that question on to ROOTS-BBS and the suggestion is : " --try the book 'Digital Image Processing' by Raphael Gonzalez published by Addison Wesley. It covers the basics and has a couple of Fortran programs. Recommendhigh frequency emphasis with contrast enhancement to start.". I hope the original poster is still around and I would like to hear more about what he was doing and how he did it!
