Solution to rotation invariance. (A) A point cloud of a tree obtained with a terrestrial laser scanner. (B) A computed SkelTre skeleton that contains the Reeb graph. The computation changes locally the function to extract the contours. (C) The extracted contours of the tree on the left colored randomly. The highlighted red boxes show a noncentered skeleton part and the extracted contours. Image taken from Bucksch et al. (2010).
