Estimating fibre twist and aspect ratios in 3D voxel volumes

摘要

Aspect ratios and twist measures can help us characterise paper fibre properties. Such measures, that need volume data, are presented here. To test the developed methods, simulated voxel volumes of fibres were created by defining each fibre as a spline curve with an elliptical cross sectional shape and a constant twist per length unit. This allows us to directly compare the measurements from the voxel volume to the properties of the original spline fibres.
