Paper fibre characterization and quantification - Automated skeletonisation and characterization for fibre deformation analysis in x-ray tomography

Abstract: With the advent of X-ray computerised tomography (CT), the possibility of capturing precise volumetric 3D images has become an invaluable tool within the material sciences. With tomographs and synchrotrons becoming more readily available to researchers and scanning time decreasing with newer equipment, the amount of data to be analysed is steadily rising. This rapid increase in data acquisition motivates the development of automatic methods to transform CT images from qualitative to quantitative data. In this work, a method to automatically characterise paper fibres from CT images based on their centre-line and mapping their deformation is presented. Methods for fibre characterisation are presented and tested on computer-generated fibres and CT images of paper fibres.
