DeepTag not only supports detection of a wide variety of existing marker families, but also makes it possible to design new marker families with customized local patterns. Moreover, we propose an effective procedure to synthesize training data on the fly without manual annotations. Thus, DeepTag ...
A ducial marker system usually consists of markers, a detection algorithm, and a coding system. The appearance of markers and the detection robustness are generally limited by the existing detection algorithms, which are hand-crafted with traditional low-level image processing techniques. Furthermore,...
The Fiducial module provides you with an easy way to identify a particular marker within the current image view. Fiducials are commonly known as "markers that are easy to identify" and are typically added to an environment where localization and navigation are needed for robots using machine visi...
Fiducial marker detection and fiducial point localization in CT images have great influence on the accuracy of registration and guidance. This study proposes a fiducial marker detection approach based on the features of marker image slice sequences and a fiducial point localization approach according to...
This work evaluates two automated algorithms for detection of intra- and inter-frame fiducial marker motion.Methods 65 patients undergoing dynamic cardiac Rubidium-82 PET imaging at rest and stress had a 1uCi Sodium-22 fiducial marker affixed to their chest during PET imaging. The 130 images (...
This section explains the experimentation carried out to test our proposal. First, the processing times required for marker detection and correction are analyzed. Then, the proposed method is compared with the state-of-the-art systems in terms of inter-marker distances, number of bit transitions,...
