Surface Reconstruction from Unorganized Points Using Kohonen's Self-Organizing Map

Computer Science Division

University of California at Berkeley

We introduce a novel technique for surface reconstruction from
unorganized points by applying Kohonen's self-organizing map.
The topology of the surface is predetermined, and a neural network learning
algorithm is
carried out to obtain correct 3D coordinates at each vertex of the surface.
Edge swap and multiresolution learning are proposed to make the algorithm
more effective and more efficient.
The whole algorithm is very simple to implement.
Experimental results have shown our techniques are successful.
