ABSTRACT We present visual methods for the analysis and comparison of the results of curved fibre reconstruction algorithms, i.e., of algorithms extracting characteristics of curved fibres from X-ray computed tomography scans. In this work, we extend previous methods for the analysis and comparison of results of different fibre reconstruction algorithms or parametrisations to the analysis of curved fibres. We propose fibre dissimilarity measures for such curved fibres and apply these to compare multiple results to a specified reference. We further propose visualisation methods to analyse differences between multiple results quantitatively and qualitatively. In two case studies, we show that the presented methods provide valuable insights for advancing and parametrising fibre reconstruction algorithms, and support in improving their results in characterising curved fibres.

弯曲纤维断层重建算法的分析与比较

摘要 我们提出了用于分析和比较弯曲纤维重建算法结果的视觉方法，即从 X 射线计算机断层扫描中提取弯曲纤维特征的算法。在这项工作中，我们将以前用于分析和比较不同纤维重建算法或参数化结果的方法扩展到弯曲纤维的分析。我们为这种弯曲纤维提出了纤维相异性度量，并将这些度量应用于将多个结果与指定参考进行比较。我们进一步提出了可视化方法来定量和定性地分析多个结果之间的差异。在两个案例研究中，我们表明所提出的方法为推进和参数化光纤重建算法提供了有价值的见解，
