ezDIC v0.1.3 - Poisson ratio export and compact GUI workflow

ezDIC v0.1.3

Poisson ratio export and GUI workflow update

This release adds a direct Poisson-ratio export workflow for users who define one axial ROI group and one transverse ROI group. It also makes the main analysis action more visible for new users.

DOI: 10.5281/zenodo.20222465

What changed

• Added ROI group roles: none, axial, and transverse.
• Added Poisson-ratio calculation from engineering strain:
  PoissonRatio = - TransverseEngineeringStrain / AxialEngineeringStrain.
• Added AxialEngineeringStrain, TransverseEngineeringStrain, and PoissonRatio columns to strain_all_groups.txt when axial/transverse roles are set.
• Added poisson_ratio.txt and poisson_ratio.png exports when axial/transverse roles are set.
• Kept failed tracking frames, missing strain values, and near-zero axial strain as NaN in Poisson-ratio output.
• Improved the right-side GUI workflow area with a compact first-screen layout, a clearer five-step beginner guide, hover tips for key workflow buttons, a prominent start button, and a separate run-status section.
• Disabled the start button during processing to reduce accidental duplicate runs.

ezDIC v0.1.1 - DOI-ready archival release

ezDIC v0.1.1

DOI-ready archival release

This release is archived by Zenodo and has a citable DOI. It adds structured software metadata for Zenodo, improves citation information, and keeps the Windows green-folder package available for researchers who want to test ezDIC without installing Python.

DOI: 10.5281/zenodo.20222465

What ezDIC does

ezDIC is a lightweight virtual extensometer for extracting linear strain from image sequences. It is intended for materials researchers who need a practical 1D strain history rather than a full-field digital image correlation analysis.

The software tracks two user-defined ROI markers and computes:

• engineering strain: (L - L0) / L0
• true strain: ln(L / L0)

where L0 is the initial ROI-center separation and L is the current ROI-center separation.

Main features

• ROI-pair tracking for virtual-extensometer strain extraction.
• Multi-ROI-group support for repeatability checks.
• Origin-compatible TXT export with Frame, EngineeringStrain, and TrueStrain.
• Engineering-strain PNG plots.
• QC summary with rejected frames, adaptive accepted frames, correlation scores, and QC level.
• Optional full CSV, correlation plot, overlay, and parameter exports.
• Windows 10/11 x64 green-folder executable package.

Why this release matters

This version is archived by Zenodo so researchers can cite a stable software record. The repository now includes:

• .zenodo.json for Zenodo metadata.
• CITATION.cff for GitHub citation support.
• LICENSE.txt and NOTICE_Attribution_and_Usage.txt for attribution and usage restrictions.
• A Windows portable package attached to the GitHub release.
