Have a look at khoros-2.2.0.0 !!! Really http://www.khoral.com/ khoros is an image-manipulation, -visualization and -analysis package for signal- and digital-image-processing. Very professional. Mostly GUI-driven. I've also tried Maple and Mathematica but they fail in the grounds (Maple does not know infinite square-functions, which are important in image-processing. When modelling infinite square-functions, they can not be FT'ed. Mathematica can not do continious FT, although there is an extra-package for this at extra cost). Now i use khoros for all the signal-processing-stuff. If you need patches and hints how to install and configure khoros, drop me an email. There are two versions of khoros available, one commercial and the other free. The difference is the documentation. The commercial version includes several books on using khoros. The free one does not. But both have the same online-documentation and there are some WWW-sites with great documentation on using khoros.
