Analysis of tomography images of bonded fibre networks to measure distributions of fibre segment length and fibre orientation

Journal article

A systematic approach to the extraction of geometrical data such as the distributions of length and orientation of fibre segments from tomographic reconstructions using a 3D skeletonization technique was illustrated. Image processing via anistropic diffusion smoothing was first performed to sharpen the fibre edges, followed by segmentation using simple thresholding. Special precautions were taken to optimize the statistical reliability of the medial axis data because the skeletonization algorithm generates a number of spurious B-B paths due to finite volume discretization. The segment length tends to increase with decreasing original fibre length and with increasing fibre volume fraction. The results show that the reconstructed fibre surfaces can be simplified into a medial axis network by employing a 3D skeletonization technique combined with suitable filtering algorithms.
