Well, in computer vision based augmented reality, you always need something as a fiducial marker.
This fiducial marker tracker is different because you can use any element of the scene as a marker.
Another thing to highlight is that an AR tracker based on SIFT allows a more robust tracking, because its keypoints are invariant to illumination changes and robust to occlusion.
Can u please provide the source code ?

Hmm, it's not clear to me why its' markerless AR. From the video it looks like it just use picture as a fiducial marker.
