Aiming at discrete dataset extract from stereo imagery matching dataset on complex terrain areas,centering on weighted average method,bilinear polynomial method,and mobile curve fitting method,the paper generates grid DEM after eliminating gross error.

This paper established interpolation model for calculating the ground settlement value of the unknown points using polyhedral function method,the weighted average method,the linear interpolation method,and the bilinear polynomial interpolation method.

A directed threshold signature scheme based on linear polynomial

Based on the basis functions,quadratic hyperbolic polynomial curves with multiple shape parameters are constructed.

The additive subgroup generated by a multilinear polynomial;

Based on the general regular simplex interest region of ( q-1 ) dimension and multilinear polynomial model,An A optimal mixture design was suggested.

With respect to the multilinear polynomial model of q-1 degree on the standard simplex Sq-1 ,this paper discusses the A-optimal design for parameter estimation and gives an algorithm of A-optimal design.

This paper introduces the basic principles,classification and characteristics of polynomial curve method,and discusses the process of modeling,and through the research on the regularity for the change of the quantity of transport facilities entering or leaving Chinese Ports,explains the application of polynomial curve method in border control intelligence analysis and prediction.
