Abstract
We introduce a novel type of markers with randomly scattered dots for augmented reality applications. Compared with traditional square markers, our markers have several significant advantages for flexible marker design, robustness against occlusion and user interaction. Our markers do not need to have a black frame, and their shape is not limited to square because the retrieval and tracking of the markers are based on geometric feature based keypoint matching. In our demonstration, we show real-time simultaneous retrieval and tracking of the markers on a laptop.
