It sounds like you might want to start investigating natural feature tracking libraries. In general the tracking is smoother and more robust than with markers, and any feature-full natural image can be used as the marker. The downside is, I'm not aware of any non-proprietary solutions.
You should look at MOPED. MOPED is a real-time Object Recognition and Pose Estimation system. It recognizes objects from point-based features (e.g. SIFT, SURF) and their geometric relationships extracted from rigid 3D models of objects.
See this video for a demonstration.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
