cubic convolution interpolation

基本解释

One method for estimating unknown data is to interpolate two dimensional terrain data. This paper presents two dimensional cubic convolution interpolation function.

In order to improve high definition video coding efficiency, a new fractional-pel interpolation algorithm based on one- dimensional cubic convolution filer is proposed.
为提高高清晰度视频编码的效率，基于一维立方卷积滤波原理提出了一种新的分像素插值滤波算法。
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。
