MechaTag: A Mechanical Fiducial Marker and the Detection Algorithm [PDF]
Journal of Intelligent & Robotic Systems, 2021 AbstractFiducial markers are fundamental components of many computer vision systems that help, through their unique features (e.g., shape, color), a fast localization of spatial objects in unstructured scenarios. They find applications in many scientific and industrial fields, such as augmented reality, human-robot interaction, and robot navigation. In

Application of Ghost-DeblurGAN to Fiducial Marker Detection
2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2022 Feature extraction or localization based on the fiducial marker could fail due to motion blur in real-world robotic applications. To solve this problem, a lightweight generative adversarial network, named Ghost-DeblurGAN, for real-time motion deblurring is developed in this paper.

Tumor track seeding: A new complication of fiducial marker insertion
Radiology Case Reports, 2014 In the United States, lung cancer is the leading cause of cancer-related death. Candidates for tumor ablation using CyberKnife® require fiducial placement in or near the target tumor to achieve precision.

Multiple Projector Camera Calibration by Fiducial Marker Detection
IEEE Access, 2023 Projection mapping has been used for various purposes in everyday situations. A key step in projection mapping is to project images and videos without distortion through calibration, which is typically performed manually.

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.
