Analysis on Four Derivative Waveforms of Photoplethysmogram (PPG) for Fiducial Point Detection
Frontiers in Public Health, 2022 Fiducial points of photoplethysmogram (PPG), first derivative PPG (VPG), and second derivative PPG (APG) are essential in extracting numerous parameters to diagnose cardiovascular disease.

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.

Prostate fiducial marker detection with the use of multi-parametric magnetic resonance imaging
Physics and Imaging in Radiation Oncology, 2017 Background and purpose: The introduction of a magnetic resonance (MR)-only workflow in radiotherapy requires that fiducial markers, used for position verification, can be detected on MR images.

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.

Tracking fiducial markers with discriminative correlation filters
Image and Vision Computing, 2021 In the last few years, squared fiducial markers have become a popular and efficient tool to solve monocular localization and tracking problems at a very low cost. Nevertheless, marker detection is affected by noise and blur: small camera movements may cause image blurriness that prevents marker detection.
