Markerless Augmented Reality on iPhone 3Gs

This video demonstrates Markerless Augmented Reality on an iPhone 3Gs.
It is done using natural feature tracking by inspecting FAST corners as demonstrated in the previous video here: http://www.youtube.com/watch?v=I4RnDjmGry8

The output is still a little choppy but I believe it can be improved with the use of filtering. The frame rate is between 30-60fps but position updates occur less frequently than frame updates. Frame processing happens on a background thread and does not affect FPS.

This is just a rudimentary demo that still requires a lot of work. I'm going to delay development for two months as I finish writing my Thesis, but will release updates after that.

Tools used in this demonstration:
iOS4 official SDK (No unofficial APIs), OpenCV 2.0, FAST corners, OpenGL ES
