Qualitative and Quantitative Architecture Characterisation of Porous Materials
D. Tsarouchas · Key engineering materials · 2011
Amethod for extracting accuratemicrostructural information fromheterogeneousmaterialsusing micro Computed Tomography ( CT) is presented. A highly porous fibrous structure is used asa case study. The proposed method includes a filtering step to increase the resolution of the gray-scaleslices, a local segmentation step to accurately separate the fibres from the background and a thinningprocedure to simplify the structure and extract quantitative statistics such as the number of fibre jointsper fibre, fibre orientation and segment length (sections between joints) distributions.
