Image Processing of Two-Phase Data for Drop-Surface Interaction Obtained by X-Ray Microtomography

Easier access to X-ray microtomography facilities has provided new insight from high-resolution imaging for various problems in drop-surface interaction research. Surface characterisation with respect to functional properties usually requires several of the following conditions: (a) imagining with sufficient resolution, (b) segmentation of the intensity data into different classes (c) triangulation and (d) curvature estimation. Two different test volumes are examined: scientific sand for discussing topics (a) as well as (b) and their influence on the example of porosity and pore classifications; and size-calibrated spheres with certificated sphericity for (c) and (d).
