By Remco C. Veltkamp
This monograph is dedicated to computational morphology, quite to the development of a two-dimensional or a third-dimensional closed item boundary via a suite of issues in arbitrary position.
By making use of concepts from computational geometry and CAGD, new effects are built in 4 levels of the development technique: (a) the gamma-neighborhood graph for describing the constitution of a suite of issues; (b) an set of rules for developing a polygonal or polyhedral boundary (based on (a)); (c) the flintstone scheme as a hierarchy for polygonal and polyhedral approximation and localization; (d) and a Bezier-triangle established scheme for the development of a tender piecewise cubic boundary.

The pair potential model is loglillear: the logarithlns of probabilities PA (π) are linear functions of the lnodel paralneters ai ,j. There is no direct relation betweell ai ,j and b i ψ and tIle (Ji ,j relative frequeIlcies are closer to the theoretical probabilities bi ,j than the estimators of ai ,j to ai ,j' The estimation of the model parameters is a typical ill-conditioned problem alld to compare different data sets , tIle bi ,j parameters may be lnore useful. The specific feature ofour data is tllat successive partitions can be either the union or the splitting of the previous one.

Finally, the potelltial of the graph r is Q(f) == ε V장 V않dβ (x ， ν) , where the summation runs on all pairs (x , ν) of vertices , d is the distance on the graph and Q , j3 > 0 are fixed constants. What is the graph which maximizes this potential for fixed number of vertices? 25 we constructed several graphs.
