The objective of the developed Avizo plugin is to compare multiple threshold types (Otsu, global and local) across a range of values, based on a previously measured hole, to eventually assist the user in choosing the suitable threshold value. The plugin .zip file is composed of the .pyscro and .rc files to be placed in Avizo installation folder. The hole data to be analysed needs to have a minimum of 2 slice images, and the orientation of the stack needs to show the diameter as circles. Further information can be found in the readme file and detailed use of the plugin is in the study titled "Development of a modular system to provide confidence in porosity analysis of additively manufactured components using X-ray computed tomography". Part 2/2: This second half of the dataset is composed of sample data used in the study and their outputs which can be found in DOI: http://dx.doi.org/10.5286/edata/901enBSD LicenceX-ray Computed tomographyAdditive ManufacturingPorosity AnalysisMetrologyAstronomical InstrumentationSoftware
