Simulation of 3D dendritic spines.

<p><b>(A)</b> Skeleton built from the set of features computed according to the multiresolution Reeb graph. <b>(B)</b> Generation of the surface between two ellipses through the triangulation of the region. <b>(C)</b> Three-dimensional representation of a spine. Once all the regions of the spine have been triangulated, the spine is a closed mesh used to visualize an artificial spine. <b>(D)</b> Improved spine representation. Loop’s subdivision algorithm yields a smoother and more accurate version of the artificial spine. <b>(E)</b> Examples of simulated spines for each cluster.
