Comparative data of ImageJ and MultiPoroX

This dataset was generated in the context of a comparative analysis of the performance of defect analysis methods in the paper: Additive manufacturing of multi-material parts – A tool for automated defect analysis.

Used software: MATLAB® R2024b, ImageJ (Version 1.54p 17 February 2025)

For both analyses the same images and parameters were used.

Used parameters:

- Resizing: None
- Scaling factor (Pixels per Milimeter): 840
- Preprocessing: Histogram Equalization (1%)
- Segmentation Threshold: 65

The analysis compared the results related to:

- Calculated Porosity
- Detected Defects
- Unassigned Material Area
- Unassigned Defect Area
- Number of Unassigned Defects

Comparison of the reference analysis using ImageJ (IMJ) and MultiPoroX (MPX)
