(Wydawnictwa AGH, 2010) Postolski, Michał; Janaszewski, Marcin Sławomir; Jopek, Łukasz; Babout, Laurent
Quantitative analysis of the human airway trees is a challenge in image processing and analysis. Results obtained in previous work on this subject are still not sufficient and they need improvements. Quantitative description of an airway tree consists in application of several steps: segmentation of the tree, skeletonization, decomposition and anatomical labelling, cross section generation and finally quantitative measurements. Each step needs to use different kinds of image processing algorithms. The most works were performed on different segmentation strategies, however skeletonization algorithms are still not enough tested and they require attention. Moreover, skeleton has very large impact on the quality of quantitative measurement of a bronchial tree. In the paper authors tested three skeletonization methods which are based on thinning - the most popular skeletonization approach. However, each algorithm uses different thinning strategy. The paper presents basic concepts of the algorithms and discussion about their primary features based on acquired results from real human CT images.
