Code for SerialTrack-XR particle tracking

Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Metadata Last Checked: August 02, 2025 | Last Modified: 2023-11-27 00:00:00
This repository contains scripts for running a custom implementation of "SerialTrack" designed for 2D X-ray projection images taken during in situ micro-X-ray computed tomography (XCT) experiments. The particle tracking-based technique allows for surface displacement and strain fields to be measured during, for example, mini-tensile test motions. This provides quantitative visualization of non-uniformities in the strain field (i.e., necking, shear banding), direct measurement of applied strain to supplement crosshead-based data, and quantification of system drift, among other uses. The code is written in Matlab and developed under Releases 2021b - 2023b under Windows 10. In total the dataset consists of about 250 MB and 79 files.
