One method for estimating unknown data is to interpolate two dimensional terrain data. This paper presents two dimensional cubic convolution interpolation function.
本文提出一种二维离散数据的插值方法——二维三次卷积插值。
Compared the three fusion methods and the three resampling techniques with themselves, the multiplicative fusion method and the cubic convolution resampling technique are relative better.
三种融合方法和三种重采样方式它们之问相比较而言，乘积法融合法和立方卷积重采样法相对较为可取。
It is acquired from that it makes use of that the interpolation function of cubic spline interpolation has a continuous third derivative on the base of two-dementional cubic convolution interpolation.
它在二维三次卷积插值法的基础上利用三次样条插值法的插值函数具有三阶连续导数的性质而得来的。
