The plans were to preserve the unearthed pieces in a museum, but doing it well would be expensive, and so it looks like they're going to rebury everything , since that worked quite well for 4050 years. I already replied by email, but I thought I should post my reply here for people who read their sites, in case they wander over. Unfortunately, it's not that simple. If you want a rule-based system that has rules at nice abstract levels, you have to feed it nice abstract data or give it a way to extract the high level features itself. Computer vision research is progressing, but it's not there yet.
Humans have systems for extracting complex high level information from images.
We can look at a picture and know whether it contains people or people-like things and can easily recognize their poses, expressions, and situations. David Forsyth , an associate professor at Berkeley, has published several papers on his research into automatically detecting naked people in images . There's also been lots of work on spotting and recognizing facial expressions and body poses, but I haven't seen anything reliable. The best thing about having a digital camera is that I take a lot more pictures than I did when I used film. The worst thing is that I'm way behind in organizing my photos.
