Planar fiducial markers: a comparative study

Virtual Reality, 2023
Fiducial markers are a cost-effective solution for solving labeling and monocular localization problems, making them valuable tools for Augmented Reality (AR), robot navigation, and 3D modeling applications. However, with the development of many marker detection systems in the last decade, it has become challenging for new users to determine which is ...

Reattachable fiducial skin marker for automatic multimodality registration

International Journal of Computer Assisted Radiology and Surgery, 2022
Abstract Purpose Fusing image information has become increasingly important for optimal diagnosis and treatment of the patient. Despite intensive research towards markerless registration approaches, fiducial marker-based methods remain the default choice for a wide range of applications in clinical practice.
