The most commonly practiced are correlation techniques, feature tracking, and fiducial marker tracking.
A novel marker tracking method has been presented and validated using simulated MR image data.
It is inferred from the comparative analysis that the method based on vertical marker tracking is not reliable.
The state-of-the-art tracking techniques include, but are not limited to, (1) marker tracking, (2) markerless tracking and (3) extensible tracking.
The results are presented in two steps: evaluation of the geometric bias in the marker tracking method, and evaluation of the performance on the marker tracking method in the presence of noise.
This permitted evaluation of the marker tracking method for different levels of noise which has not been done previously.
Deformation can be measured using marker tracking methods applied to full volume scans taken at each deformation step.
The method exploits the transparency and room-temperature ductility of silver chloride, and combines the techniques of photoelasticity and marker tracking.
The strain measurement techniques include digital image correlation (DIC) and two techniques of video-based extensometry: marker tracking and area variation monitoring.
