Wanna know about Fiber Walks?
Fiber Walks are self-avoiding random walks that include lateral expansion. Lateral expansion is perpendicular to the growth direction and constructed as a contraction of the square lattice in which a fiber is growing. The research of lateral expansion resulted in fascinating features like faster divergence from the origin compared to the unexpanded walk or the existence of areas where branching is necessary to reach them with a growth process.
The fiber walk is inspired by the growth of plant roots and parallels experimental discoveries as well as providing new theoretical discoveries.

We made an interactive web page to investigate the results of the CAMPINO Algorithm, which was our first skeletonization algorithm. You can turn around an example point cloud an see the distances to the skeleton in different resolutions. You need Java to be enabled in order to use the applet. Enjoy ! Link to applet.
My P.h.D. research was carried out at chair of Optical And Laser Remote Sensing (OLRS) at the Delft University of Technology under the supervision of Roderik Lindenberg and Massimo Menenti.
