In applications of augmented reality or virtual reality, fiducials are often manually applied to objects in a scene so that the objects can be recognized in images of the scene → Fiduciary_marker

- reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers attached onto physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces (TUI) and multi-touch interactive surfaces.
ARTag “Magic Lens” and “Magic Mirror” systems use arrays of the square ARTag markers added to objects or the environment allowing a computer vision algorithm to calculate the camera “pose” in real time, allowing the CG (computer graphics) virtual camera to be aligned.
