We did some new experiments with augmented reality and used the cam-image as marker overlay. You can download the software with the results of our experiments. It was made withprocessingand theNyARToolkit. We did some modifications to let it work with GStreamer.The software is developed and tested with Linux (Ubuntu 10.04) but the untested versions for Windows and OSX should also work.
Download the software for your OS (Linux, Windows, OSX)
