Percolating length scales from topological persistence analysis of micro-CT images of porous materials

Robins, Vanessa; Saadatfar, Mohammad; Delgado-Friedrichs, Olaf; Sheppard, Adrian P.

Description

Topological persistence is a powerful and general technique for characterizing the geometryand topology of data. Its theoretical foundations are over 15 years old and efficient computational algo-rithms are now available for the analysis of large digital images. We explain here how quantities derivedfrom topological persistence relate to other measurements on porous materials such as grain and pore-sizedistributions, connectivity numbers, and the critical radius of a percolating sphere. The...[Show more]
