Generation of skeletal structures for the pelvis area with the use of 3-dimensional binary thinning algorithm

The article presents the use of 3-dimensional thinning algorithm in creation of skeletal structures describing the area of pelvis and its surrounding. The skeletal descriptors are created for the models of pelvis and femurs and further transformed from its voxel representation into the graph. The result of the skeletonization is compared with the Reeb graphs created for the same bone models. The usefulness of the skeletons for the morphing algorithm is discussed.
