  For the analysis of systems consisting of small, regular objects, the methods
of mathematical morphology applied to images of these systems are well-suited.
One of these methods is the use of Voronoi polygons. It was found that the
Voronoi tessellation method represents a powerful tool for the analysis of thin
film morphology and provides nanostructural information to many multi-particle
assemblies. In these notes, several morphological algorithms are analyzed and
we study how to join all of them to design a graphical user interface (GUI)
that provides as input for the system the "AFM image" and interprets the output
of the system in terms of errors and generators coordinates.
