    In this paper problem of airway tree segmentation from 3D CT chest scans was considered. Especially comparison of two authors' algorithms was provided. The algorithms are 3D region growing approaches. The first method uses hole closing algorithm in order to avoid leakages into the lungs. The second approach guides and constrains region growing by morphological gradient. Results of both considered methods for exemplary data are presented and discussed.

    The thesis presents detection orientation of cracks on the rock walls. The Different edges of the detection algorithms were compared. The main purpose of this dissertation was built the program „Róża Kierunków” in matlab. Based on the results it was concluded that the best algorithm for detection orientation of cracks on the rock walls is using morphological gradient.
