We describe a new method for 2D fiducial tracking. We use region adjacency information together with angles between regions to encode IDs inside fiducials, whereas previous research by Kaltenbrunner and Bencina utilize region adjacency tree. Our method supports a wide ID range and is fast enough to accommodate real-time video. It is also very robust against false positive detection.
