Testing a steganalysis technique on realistic data I'm developing a new image steganalysis technique, and I'd like to test how effective it is in practice.  How could I do this?  Are there such things as standard "test vectors" for steganalysis?

Not that I am aware of.

Your best bet would be to look for steganographic systems that are out there (either software or a paper describing it). Implement those systems and see how your steganalysis method works. Then you can implement other steganalysis methods from the literature and compare how well yours does vs those.
