I am interested in finding about Image Enhancement programs. I wish to use these to enhance old (25-40 year) photographs. Most of the photographs are black and white. Examples of image enhancements would be: contrast increase, smoothing cracks due to folding, smoothing of small peeled off areas etc. Information about libraries/code would also be welcome. Is NASA/JPL or other government enhancement software available to "the public?" I know very little about image processing. Thanks. Deven Kalra kalra@hplvis.hpl.hp.com

Yes. In general, software developed by taxpayer money is freely available. However, in order to get the "free" software, you have to go through official channels, and get charged for distribution costs (i.e. pay for bureaucracy). In the case of NASA-developed software such as VICAR, JPL's image processing package, you have to get it from an outfit called COSMIC, which charges a fairly large amount of dollars for sending you a tape or two and a manual. You can contact COSMIC for information on *buying* the software catalog at: COSMIC The University of Georgia 382 East Broad Street Athens, Georgia 30602 Phone: (404) 542-3265 FAX: (404) 542-4807 That said, you probably don't want VICAR anyway. The COSMIC version lags many years behind the "real" version, which still only runs on VMS systems, supports only a handful of (usually expensive) display platforms, and has all the characteristics you'd expect of a collection of programs which were developed on an IBM mainframe beginning around 1969 and were ported to VMS. VICAR runs best when you can go down the hall to talk to the person who wrote a given VICAR program, i.e. at JPL. COSMIC definitely doesn't have the facilities to provide technical support for something as ponderous as VICAR, and the network community in general doesn't use VICAR, and hence there isn't a large peer support network around as there is for various other packages. -- Joel Plutchak, Research Programmer/Analyst Brown University Planetary Geology
