[comp.graphics] Curve Analysis

         Dear Professionals
I would appreciate any hints to the following family of problems:

     INPUT :  A set of points in the 2D - plane
   
     OUTPUT : An estimate of the analytical description of the curves
              that are composed by the points.

     EXAMPLE :    An appropriate algorithm should tell me that 

                                            *    
                    ******                  *
                         *                  *

                   are two sets of curves, where the first consists of two curves
                   connecting at '?' and the second is only one curve -- together
                   with an estimate  PHI(u) = { x(u), y(u) } of the parametrical
                   description of all curves.


                
             Thank You for Your attention.
