Title 3D Tracking of Cellulose Fibres
Abstract Segmentation of individual cellulose fibres in volume images is an important step in the analysis of the three dimensional (3D) fibre structure in paper and fibre composites. On the seminar I will present a new method for 3D tracking of individual fibres which can be used as a pre-segmentation step to a full cell wall segmentation or be used to estimate the fibre orientation. The tracking of each fibre starts in a seed point and automatically extracts the local fibre orientation and the fibre centre point in each step using 3D information in a local coordinate system that follows the local fibre direction.
