The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use https://opara.zih.tu-dresden.de/ for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.

Zugrundeliegende ForschungsobjektePhysicalObject: soil, granular matter
KurzbeschreibungThese files serve as the basis for a benchmark study on the image analysis to extract contact fabric from x-ray tomographies of granular materials. They are based on the python package "spam": The Software for the Practical Analysis of Materials -- that will soon be open source and installable via pip. For the moment (as of 2018-08-24), see: https://ttk.gricad-pages.univ-grenoble-alpes.fr/spam/intro.html#welcome-to-spam These files support the publication: A benchmark strategy for the experimental measurement of contact fabric
Angewendete Methoden oder VerfahrenThe data on fabric and its evolution were created with the discrete element software WooDEM (https://woodem.eu/).

  • A benchmark strategy for the experimental measurement of contact fabric [2]Open Access Icon
    This work develops a strategy to benchmark image analysis tools that can used for the determination of contact fabric from tomographic images. The discrete element method is used to create and load a reference specimen for which the fabric and its evolution is precisely known. Chosen states of this synthetic specimen are turned into realistic images taking into account inherent image properties, such as the partial volume effect, blur and noise. The application of the image analysis tools on these images validates the findings of the metrological study and highlights the importance of addressing the identified shortcomings, i.e., the systematical over-detection of contacts and the strong bias of orientations when using common watersheds.
